About us

Editorial policy

Where the facts come from, and what stays out.

Every rule, number and season on Which Pest in New Zealand comes from a public source listed at the foot of the page.

Where the facts come from

  • Health New Zealand and the National Poisons Centre, for bites, stings and poisoning.
  • MPI and DOC, for biosecurity, introduced pests and wildlife.
  • Te Papa and universities, for what a pest looks like and how it lives.
  • The EPA, for the rules on hazardous substances, never a manufacturer's marketing.
  • Tenancy Services and Settled.govt.nz, for renting and buying a home.

What stays out

We make no claims about how safe a pesticide is, and we promise no results. Only the business doing the work can tell you what its products are and how they're used, so we tell you what to ask instead.

There are no prices, rankings or reviews from us here, and no DIY steps for anything that could hurt you, like spraying a wasp nest or climbing around in the ceiling space.

Safety lines

Where a pest can hurt someone, the page says what to do first, using public numbers only: 111 in an emergency, and the National Poisons Centre on 0800 764 766 for poisonings. We have no phone number of our own to give.

Keeping it current

Biosecurity advice and tenancy rules change. We review pages regularly, and anything that changes the advice gets updated when we find it.

Some of the photos on this site are illustrations made with an AI image tool. None of them shows a real job or a business in our network.
