Short answer. At 2 Nov 2026 the rules are in transition. The national freshwater farm plan system is being rewritten, with a 50 ha threshold for pastoral and arable farms, and farmers don't need plans in place until the new regulations are finalised. Waikato Plan Change 1 still exists, but key farm plan and consent dates are proposed to be pushed out to 31 December 2032.
What's happening, in order
| Item | Status at 2 Nov 2026 | Source |
|---|---|---|
| Freshwater farm plan threshold | 50 ha or more of pastoral, arable or mixed land, 5 ha or more of commercial vegetable or other horticulture, or a commercial dairy farm. The old 20 ha threshold has been lifted. | Ministry for the Environment, checked 2 Nov 2026 |
| When plans are needed | Not until the regulations are finalised. The MfE page says that is expected later in 2026. | MfE, checked 2 Nov 2026 |
| Certification and audit | Only where higher-risk activities happen, such as dairy farming, grazing pigs, commercial vegetables or feedlots. For sheep and beef, intensive winter grazing or irrigation on more than 50 ha or 10 percent of the farm (whichever is greater) is the trigger. | Government media release, 19 Aug 2026 |
| Timeframes | Five years from when the system is switched on to prepare and certify or declare plans. Recertification every six years. | Same release, 19 Aug 2026 |
| Earlier Waikato Regional Council farm plan dates | These pre-date the national changes. Check with the council before relying on any old date. | WRC info sheet |
Waikato Plan Change 1 (PC1)
PC1 covers farming and land use in the Waikato and Waipā river catchments. It hasn't been cancelled. DairyNZ's September 2026 update says:
- The Government's direction would defer the PC1 farm environment plan and farming resource consent requirements until 31 December 2032. DairyNZ describes this as proposed.
- Existing farming still operates under a permitted activity rule with conditions on nitrogen fertiliser, cultivation, intensive winter grazing and sacrifice paddocks.
- Land-use change over 4.1 ha stays controlled and may need consent. DairyNZ says those controls have been in place since 2016.
The Natural Environment Act 2026 received Royal Assent on 29 September 2026 (NZ Parliament). Whether the PC1 date deferral described above is now in force is not confirmed here. Waikato Regional Council has said it will publish an updated PC1 once the legislation and Environment Court steps are complete, so check its PC1 page for the current dates.
What this means if you're buying or selling
- Ask the vendor whether they hold a farm environment plan or any plan, even a voluntary one. It's useful evidence of how the farm's been run.
- Ask what land-use change or intensification has happened in the past few years, and whether any consent was needed.
- For a dairy or dairy support farm, check effluent compliance (see farm dairy effluent) and any stock exclusion work still to do.
- For sheep and beef, check intensive winter grazing practice and whether any crop paddocks are near waterways.
- Put the question to your solicitor: is the farm subject to any consent conditions that transfer to a buyer?
