A microchip is the surest way to get a lost pet home. In New Zealand, most dogs are legally required to be microchipped - here's how it works and what to keep in mind.
How microchipping works
A vet implants a tiny chip, about the size of a grain of rice, under the skin between the shoulder blades. It carries a unique number linked to your contact details on the New Zealand Companion Animal Register (NZCAR). A vet or shelter can scan it and get you called.
Is it the law?
- Most dogs must be microchipped and registered under the Dog Control Act
- Working farm dogs are the main exception - ask your council
- Microchipping cats isn't compulsory, but it's strongly recommended
Keep your details up to date
The chip is only as good as the contact details attached to it. If you move house or change your phone number, update the NZCAR - an out-of-date chip can't reunite you with your pet. We're happy to help you check.
