First published in NZ Winegrower, December 2013 – January 2014
The Government has recently released proposed amendments to the National
Policy Statement for Freshwater Management 2011 (the NPS)
following recommendations by the Land and Water Forum (as discussed in a
previous issue of NZ Winegrower) that a national instrument should
establish a national objectives framework under which regional councils set
freshwater state objectives at a regional/catchment scale. The main proposed
amendments are briefly discussed below.
Accounting for all water takes and contaminant
It is proposed that councils will be required to establish and operate a
water quality and quantity accounting system either based on measurements,
modelling results, or estimates. The information is to be recorded at the level
of the management unit which can be set as large or as small as councils
consider appropriate (for example multiple catchments or part of a catchment).
The information must be updated at least every five years for water quality and
annually for water quantity.
The accounting information must be available when setting or reviewing
limits. The rationale is that making good decisions on limits and how to manage
within them requires good information on existing resource use, with an
assessment of all water takes and all sources of relevant contaminants including
diffuse discharges and those permitted by regional plan rules.
Establishing a national framework to support communities setting
It is proposed that the national objectives framework be included in the NPS
to provide councils with scientific information and a process for setting
freshwater objectives. The framework includes: a set of freshwater values and
uses with narrative descriptions of each; a set of attributes associated with
some of the values and uses including ranges of numbers that represent different
states that the attribute may be managed for; and a process for setting
freshwater objectives at the chosen attribute states to provide for the chosen
values of freshwater management units.
As part of the freshwater objective setting process, councils and communities
must consider all of the values and uses of water bodies and decide whether they
apply in each freshwater management unit. The framework assists in ensuring that
the values are achieved to a minimum level (for example, the water body being
fit for swimming). Leading scientists from across New Zealand have been involved
in developing and testing the technical information in the framework, so by
including it within the NPS this prevents unnecessary duplication and cost.
Establishing compulsory national values in regional
The Government has determined that some values are so important to all New
Zealanders that they are likely to apply to all water bodies. These are
ecosystem health and human health for secondary contact recreation. The
framework sets out a number of proposed attributes for these values in terms of
numeric states (such as E. Coli and nitrate toxicity) but it is
intended more attributes will be proposed for the next few versions of the
Introducing national 'bottom lines' for ecosystem and human
It is proposed that the NPS defines minimum acceptable states called
"national bottom lines", for each of the attributes for ecosystem health and
human health. These bottom lines set the minimum level at which the compulsory
values are provided for. The Government considers that the quality of most water
bodies is already above the proposed bottom lines, but where these are not
currently met freshwater objectives would need to be set at the bottom of what
is described as the "C state" or better for all attributes relating to ecosystem
health and human health for secondary contact recreation unless the criteria for
an exception can be met as discussed below.
Including restricted grounds for exceptions to 'bottom
It is suggested that a regional council would be allowed to set a freshwater
objective below a national bottom line in narrowly defined situations (after
public input during the planning process including submissions and hearings). It
is stated that exceptions are needed to recognise circumstances where it is not
feasible or possible to improve water quality to the required level. The
exceptions are where a freshwater management unit is contaminated from natural
processes or it has been subject to historical activities that have created
lasting impacts on water quality and the reversal of those impacts is not
reasonably practicable, either physically or ecologically, even in the long
The Government also proposes that it will be able to decide after applying
criteria if an exception should be made where water quality is affected by
significant existing infrastructure. For example, hydroelectricity generation.
