One Plan Reviews and Changes

Planning documents need to be brought up to date from time to time, and the One Plan is no different. This can be prompted by a new or changed policy direction or standards from central government, or can follow an evaluation of how well the regional policy statement and regional plans are working. If an evaluation shows that something could be improved, a review is then carried out to work out what options will best deliver the Plan's objectives, and whether changing the Plan is sensible.

Even if evaluations don't reveal any issues, the Resource Management Act requires that every part of every planning document has to be reviewed at least every 10 years. Amendments may also be made without a formal plan change process when required by a national policy statement or environmental standard, for example.

Horizons is also developing a catchment planning programme, Our Freshwater Future, working with local communities to develop broad-based action plans for continued improvements to freshwater quality in the region. Our Freshwater Future isn't focused on regulation but will, in time, inform future Plan changes. The first of these processes will begin in the second half of 2018 and will focus on the Manawatū Catchment.

One Plan Evaluation

The One Plan was made operative in December 2014. Since then we have evaluated the following topics:

Freshwater quality (2016). This lead to a more detailed evalution of the One Plan's nutrient management provisions (2018).



  • PPC2 - application for streamlined process to Minister for the Environment October, 2018

  • Our Freshwater Future - commencement of Manawatū Catchment Strategy process November, 2018 to December, 2018

  • PPC2 - anticipated notification December, 2018 to February, 2019

    Timing depends on the Minister's decision on our application for a streamlined process

  • PPC2 - anticipated decision June, 2019 to August, 2019

  • PPC3 - projected notification July, 2019 to September, 2019

    Will occur after Plan Change 2 has been finalised

Plan Change 1

This plan change took effect on 28 April 2016. It inserted a new policy into Chapter 14 of the One Plan (required by the National Policy Statement for Freshwater Management), consequential amendments and correction of some minor errors. You can see the amendments made and the reasons for them in the report to the Strategy and Policy Committee meeting on 12 April 2016 and its annex.

Plan Amendment 1 - Forestry

This minor amendment to comply with the National Environmental Standard for Plantation Forestry took effect from 24 September 2018. Rule 13-3 and the definition of 'forestry' are amended by Plan Amendment 1. You can see the amendments in the report and Annexes A (Chapter 13) and B (Glossary) to the Strategy and Policy Committee meeting on 14 August 2018.

Proposed Plan Change 2

In 2017 an evaluation of the policy for managing nutrients in Horizons’ Regional Plan (the One Plan) demonstrated that a problem exists within the regulatory framework. Proposed Plan Change 2 (PPC2) will recalibrate Table 14.2 with OVERSEER© version 6.3.0 and focuses on the controlled activity pathway for managing nutrients.

Council has considered the appropriate planning process to use for this plan change standard or streamlined and has resolved at the 25 September 2018 meeting to apply for a direction from the Minister for the Environment for a streamlined planning process. The aim is to apply to the Minister before the end of October 2018.

Proposed Plan Change 3

We expect to carry out a more comprehensive plan change, also focused on the One Plan's nutrient management provisions. The aim is to notify Proposed Plan Change 3 (PPC3) following the completion of PPC2 - this is likely to be in the second half of 2019.
