In March 1996 the writer presented a paper to the New Zealand Petroleum Conference entitled "Gas - An Overview of the Legal Framework".
My aim in this paper is to update the position so as to give you a perspective of the structural elements of the gas market and the various transactions that have rung the changes.
I should also add that this paper is mainly concerned with gas contracts. Oil production is usually the major commercial objective of most explorers. However, leaving aside the start of oil production from Maui, an event which was the subject of much discussion at the last conference, and the increased levels of exploration activity there has been little of financial significance to occur in the upstream oil industry in New Zealand over the last two years. However, all New Zealand's fields produce gas in association with liquids production and it is frequently the case that gas contracts are very significant value drivers for those fields and for the major participants in the industry. Thus the focus for this paper.
My paper in 1996 described the key elements of the major contracts that shape the overall structure of the New Zealand gas industry. Thus the paper included a description of the interlinked relationship of all of the major gas contracts then operating in New Zealand. Contracts involving less than 5 PJ per annum were not dealt with because, in the then overall structural context, they were of only marginal influence, even if they were very important to the parties to those contracts.
Since then various circumstances and events have had a marked effect on the overall texture of the New Zealand gas market. Many of the rigidities that were in evidence have now been dismantled and the result is a market place that is much more dynamic and where there is evidence of real competition occurring between active participants.
There are 5 key events that have brought about these changes:
Perhaps the most important change to the overall dynamic of the New Zealand gas market has been the emergence of Contact Energy Limited as a significant gas trader.
Contact is a state owned enterprise that was formed in 1996 and commenced business in March 1996, that is, about the same time as the last New Zealand Petroleum Conference in Auckland.
Contact was formed as a result of the split from ECNZ of some of ECNZ's electricity generation assets. The policy objective was to create a second large competing electricity generator. As I noted at the last conference Contact has taken over all of ECNZ's Maui purchase obligations and entitlements and all of ECNZ's then contractual obligations to buy gas from the Tariki/Ahuroa, Waihapa and Ngaere fields (the TAW contract).
As part and parcel of the Contact/ECNZ split, ECNZ entered into gas purchase obligations with Contact. This served two purposes, ECNZ became a substantial customer of Contact and ECNZ secured a supply of gas for its Huntly power station.
There has been no information made publicly available about the key elements of the Contract/ECNZ contractual arrangements. Thus we do not know:
However, we do know from ECNZ's published documents that for the year to 30 June 1997 ECNZ burned 48 PJ of gas, all but 5 PJ of which it would have acquired from Contact.
The assignment of ECNZ's rights to the TAW Contract to Contact involves a committed purchase by Contact of 9 PJ per annum. However, Contact also picked up the obligation to on-sell that gas to FCE for use as a fuel source for the Taranaki Combined Cycle power station near Stratford.
The situation that existed as at the start of 1996 can be depicted as follows:

During the course of 1996 it became clear that Contact's gas purchase obligations (under its take or pay contract with the Crown for Maui gas and in respect of TAW gas) exceeded the purchase commitments from ECNZ, FCE and Contact's then expected own use requirements.
It is little wonder therefore that dealing with its surplus gas entitlements (and resulting take or pay obligations) has become a major activity for Contact. Indeed in Contact's Statement of Corporate Intent for the year to 30 September 1998 it is stated:
"Contact's core business is primarily the generation, marketing and trading of electricity and the purchase, marketing and trading of gas."
In their 1997 annual report Contact noted:
"A special challenge to our company is the judicious management of our gas portfolio and contractual commitments under take or pay obligations to the Crown."
Thus, in a nutshell, Contact has a significant commercial incentive arising from its substantial gas purchase obligations and entitlements, has the means in terms of financial power and analytical skills and a clearly stated commercial intent to enter the gas market as a substantial and active trader.
Since March 1996, Contact has concluded a number of arrangements that reflect these commercial imperatives.
Annual Quantity 6PJ
Price Approximately $2.70 per G
The gas price is on a fully delivered basis at Rotawaro. The term of the contract appears to be for a number of years but again these details have not been announced.
However, this is not all that Contact has done.
There are various indications that Contact continues to be a new and competitive force in the market place. Contact is in a special position because, under the terms of its Maui purchase rights it can take delivery of Maui gas at any point along the Maui line. This is of particular significance because, as a result, Contact has no requirement to pay NGC any delivery costs associated with transporting gas from Taranaki through to Huntly.
Thus Contact has, if not an outright competitive advantage, at the very least substantial equality with other would be gas suppliers such as NGC. Contact is at an advantage, in this respect at least, as compared to (say) the Kapuni Mining Companies and FCE, each of whom will have to pay transmission costs to get product to the more northern markets.
The transactions just referred to are concrete evidence of the emerging position of Contact as a gas trader.
Contact's position is now:-
Contact's position as at early 1998

In my 1996 paper it was noted that litigation concerning the Kapuni contract was scheduled for a hearing in the Auckland High Court commencing May 1996. Despite various efforts to settle the litigation the case in fact proceeded to trial during the course of 1996 and was heard over a period of 48 days. The final submissions were presented in early August 1996. The judgment of the court was eventually handed down 3 February 1997. As a result of difficulties associated with sealing the Courts judgment a further supplementary judgment was handed down on 26 May 1997.
It is unnecessary to traverse the arguments presented during the course of the case or to analyse the judgment of the High Court because this is a subject of a separate paper later in the conference. Conference delegates will have the opportunity on Wednesday to not only hear a legal analysis of the judgment but also to hear the views of representatives of two of the main protagonists in the case, Mr David Kirk from Fletcher Challenge Energy Limited and Mr Richard Tweedie of Todd Petroleum.
At the risk of grossly oversimplifying matters the key outcomes from the case can be stated as follows:-
As noted in my earlier paper, in the realm of gas contracts the devil lurks in the detail. Thus what was no doubt considered to be an admirably elegant solution left unanswered a number of very important questions. For this reason a supplemental judgment was sought.
It appears that both sides to the litigation were less than entirely happy with the outcome of the case and there was considerable talk of possible lines of appeal. However, the parties were able to negotiate a settlement, the key ingredients of which being:-
However, this analysis does not truly capture the significance of the end result. What has occurred is that there is now a major, well funded and technically capable consortium able to sell large quantities of gas which is to be produced from a location very close to all the essential infrastructure needed. The KMCs are unconstrained by any existing contractual obligations and can sell up to one half of the Maximum Daily Quantity (approximately 20PJ per annum) into the market place. The KMCs therefor now represent a very significant potential source of supply to large scale consumers (other than electricity generators).
The Kapuni Mining Companies have quickly moved to take advantage of this situation and are already the suppliers of significant quantities of gas to the Kiwi Co-operative Dairy for co-generation purposes. There can be little doubt that various other initiatives will be being actively pursued.
The 1996 paper noted that litigation had been commenced by NGC against Enerco concerning the take or pay obligations contained within the 1980 contract between Enerco and NGC. By mid 1997 the litigation was at a point where it was ready to be set down for trial. However, as is often the case as the realities and risks of a protracted trial become apparent, the parties attempted yet again to resolve the differences through settlement negotiations. This time the negotiations were successful.
Key drivers that influenced a settlement included:-
Thus in September 1997 the NGC/Enerco was settled, the overall effect of which being that:
The new gas supply terms, as announced by Enerco and NGC are as follows:
Almost at the same time as the NGC/Enerco settlement was announced, and as already noted, Enerco also announced that it had entered into contractual arrangements to be supplied with gas by Contact. This event signalled the introduction of another new and substantial seller of gas into the New Zealand market. The Contact/Enerco agreement represents the most significant charge to the structural elements of gas supply to retailers almost since the reticulated natural gas industry first began.
Thus from a situation two years ago where New Zealand's largest gas retailer was contractually tied to one supplier on terms that could be said to have been long past their "use by" date, we now have a situation where that retailer has two sources of supply, and, as its market grows, has the ability to access further supplies from other sources. Indeed, Enerco is also now an active explorer in its own right as it seeks to better manage the cost of its gas supply.
On 7 July 1997 the Gas (Information Disclosure) Regulations 1997 were finally promulgated and came into force 7 August 1997. While these Regulations had long been anticipated they are now a reality. New Zealand does have an open access gas transmission network.
A more detailed analysis of the gas transmission network and the open access regime will be presented later at this conference.
However, for purposes of this paper, the key point to note is that any party seeking access to the gas transmission network now has clear rules and guidelines which can be followed and upon which pricing and terms will be based. Whatever the different protagonists may feel about the economic efficacy of the pricing regime as promulgated by NGC it is nevertheless a significant step forward from the highly uncertain position that existed as at March 1996.
It is now possible to assess likely transmission costs in advance of any contractual commitment and to be confident that the same rules will apply to all.
In early 1997 attention became focussed on the Kupe field. In February 1997 FCE acquired a 20% interest in the Kupe field from Norcen. But this was only the start.
In March 1997 Fletcher Challenge Energy and ECNZ each acquired in the names of subsidiaries and through a joint vehicle, an aggregate 40% interest in the Kupe field which was achieved as a result of the purchase of the interests of Western Mining. The combined ECNZ and FCE interests in Kupe are now 62.5%
The Kupe field contains probable reserves of approximately 250-300 PJ. However, as has been noted elsewhere, the field requires further appraisal drilling and, on almost any basis of economic analysis, the economics for development of this field are difficult. Development will only be able to occur if a substantial gas contract can be entered into between the owners of the field and a gas purchaser and at gas prices that are likely to be considerably in excess of those payable under either the Maui contract or likely to be paid with respect to any purchaser of Kapuni or Mangahewa gas.
While it is not the province of a legal adviser to make economic predictions concerning the developments of oil and gas fields, other events since March 1997 (in particular the possibility that Mangahewa is a significant discovery) make it difficult to foresee early development of the Kupe field.
The acquisition by ECNZ and FCE of the Kupe interest from Western Mining is also set to become the subject of judicial scrutiny. Late in December 1997 the Commerce Commission commenced proceedings against Fletcher Challenge Energy and ECNZ alleging that the acquisition and the Generic gas contract, dealt with below, are in breach of the Commerce Act. Needless to say both defendants have said they will be vigorously defending themselves.
What can be said is that this litigation will no doubt be yet another examination of the nature and extent of the activities of Fletcher Challenge Energy in the New Zealand gas market place. In light of the various transactions canvassed in this paper it will also be interesting to see what market definitions are now considered appropriate.
A key exploration and development highlight of 1997 has been the successful efforts to obtain production from Mangahewa. How this was achieved and the engineering and geological implications is the subject of a separate paper. In terms of its commercial implications it is a very exciting development indeed.
Mangahewa is located in very close proximity to:
The field seems to be capable of producing in substantial volumes and, even if fracturing is an expensive process, the costs of development are clearly likely to be much lower than the costs of development of any offshore field. The gas is of high quality and requires relatively little processing and, while not spectacular, has a useful associated liquid stream to assist the overall economics.
The indications appear to be that the reserves from this field are substantial but obviously further appraisal drilling will be necessary.
Mangahewa is potentially the new low cost high volume gas producer in New Zealand. Mangahewa therefore could very substantially alter the commercial dynamics for gas production in New Zealand.
In September 1997 Fletcher Challenge Energy and ECNZ announced that an agreement had been concluded whereby Fletcher Challenge has agreed to sell 20 PJ per annum of natural gas to ECNZ over a 17 year period.
The most interesting aspects of this announcement are:
FCE and Methanex signed a memorandum of understanding in the latter part of 1997 pursuant to which they each agreed to investigate the possibility of FCE being a substantial supplier of gas to Methanex. The lawyer in me suspects that there is not much in the arrangement that is enforceable in any conventional sense. However, taking a broader view, it is a very clear signal between two of the leading industry players of their desire to work towards common goals. The fortunate position of Mangahewa directly beneath the two methanol plants and the now progressive decline of Methanex's Maui gas delivery entitlements mean that some of the key commercial elements to ensure this understanding can be commercially consummated are in fact in place.
Late in 1997 NGC and Methanex announced an arrangement whereby Methanex has purchased from NGC some 25 PJ of NGC's prepaid gas entitlements. In effect, NGC has sold for value today a future entitlement to prepaid gas. For its part, Methanex has paid value today for an entitlement to be delivered prepaid gas for no payment at some time in the future. An interesting aspect of this transaction is its innovative nature. However, the most important thing about the transaction, namely, the value paid for the prepaid gas entitlements is unfortunately not the subject of any announcement - we are left having to speculate what that value might be.
For the sake of completeness mention should also be made of a transaction that took place in early 1997 between ECNZ and NGC for a spot sale of 5 PJ of gas by NGC.
It is unlikely that this transaction will be a precursor to the development of any more broad based spot market. Again, however, it does illustrate the willingness of participants in the industry to take advantage of a perhaps isolated situation and to pursue value wherever it might appear. The size of the transaction is not particularly big but clearly demonstrates the desire of key participants to seek out as much flexibility as possible.
The various transactions described in this paper demonstrate that there are new dynamics at work in the market place for gas within New Zealand.
Thus, we have a new and committed gas trader in the form of Contact Energy - an organisation with access to large quantities of gas, favourable transmission entitlements because of its Maui purchase rights and which has the balance sheet and analytical ability to actively pursue value wherever it sees it.
We have the ability in New Zealand for the two longest established and arguably most experienced gas producing companies, Shell and Todd, to aggressively enter the market because of their new entitlement to directly sell Kapuni gas. The volumes they are able to sell are substantial.
NGC now offers unbundled energy and transmission arrangements. Would be sellers of gas can now work out in advance the cost of transmission and securing capacity rights. NGC has also demonstrated its willingness to become a more nimble competitor by reason of:
NGC has thus demonstrated an ability to adapt to the changing market circumstances.
Our largest gas retailer, Enerco, has been released from its exclusive supply arrangements with NGC. Enerco has taken advantage of this by immediately entering into arrangements with Contact. As is obvious from other papers at this conference, Enerco is clearly seeking to further diversify its upstream supply arrangements by direct participation in ongoing exploration efforts both in Taranaki and elsewhere around New Zealand. Enerco is thus also showing a determination to be nothing other than a dynamic participant in the market.
Accordingly we have seen and will continue to see more and different arrangements being entered into as participants seek value. It is likely to be the case that smaller scale transactions will become more common and more sought after as all participants seek to preserve for themselves flexibility and to obtain value wherever it might appear.
We are also seeing the breakdown or even abandonment of the old characterisation of participants in the market place. Descriptions of participants as generators, producers, petrochemical companies, wholesalers or retailers simply do not do justice to the dynamism and flexibility apparent across the whole market place. Thus, we have Contact selling gas to retailers, using gas for its own use, selling gas to other wholesalers to onsell and selling gas to petrochemical clients.
NGC, which has been described as a gas wholesaler, now sells gas entitlements to petrochemical companies, has sold gas to an electricity generator in the form of spot sales to ECNZ, as well as sales to other retailers and its own use plus co-generation sales. In other words NGC now sells to many different markets wherever it can obtain value.
Methanex is sourcing its gas from each of the Crown, NGC and perhaps FCE but could be supplied in future from all of these companies plus Shell/Todd and Contact.
ECNZ has sought to move upstream to secure gas supply by acquiring a stake in the Kupe field and entering into generic gas supply arrangements with FCE.
When I last spoke to you in 1996 the market was relatively static and characterised by several long standing, often contested contracts. In the two years since a lot has changed and all the signs are there for this new dynamism in the market to continue.
