The NPF and NBE plans will include outcomes for the natural and built environment.
Examples of outcomes include things such as protecting and restoring estuaries and coastal areas, reducing greenhouse gases, and developing climate-resilient urban areas.
NBE plans will show how the outcomes will be achieved through its policies, methods, and rules for consents.
An important part of developing an NBE plan will be identifying and resolving any conflicts between different outcomes. The NPF will give guidance on this.
The new system will also set limits and targets to help protect and improve the environment and human health. Limits and targets will be set nationally in the NPF, or locally in NBE plans.
Environmental limits are similar to the ‘national bottom lines’ in the National Policy Statement for Freshwater Management 2020 and aim to avoid any further environmental degradation. Development won’t be allowed to breach environmental limits, and each limit will have a related target to drive improvement.
Human health limits are about ensuring the natural environment is in a state that’s acceptable for human health. Areas above the human health limit mustn’t decline, and areas below the human health limit must improve.
Limits and targets will be set in six areas: air, indigenous biodiversity, coastal water, estuaries, freshwater, and soil.
An expert panel will review the science and evidence, including mātauranga Māori, that underpins potential limits and targets before they’re finalised.
