Dog Fences in NZ: Physical, Electric & GPS Options and What the Law Requires

What the law requires at home

Control or confinement. Section 52A of the Dog Control Act applies when your dog is on land you occupy. You must, at all times, make sure either the dog is under the direct control of a person, or it is confined within the property in such a way that it cannot freely leave. If you don't, a dog control officer can seize and impound the dog, and you can be fined. The infringement fee is $200 (Schedule 1), and the maximum court fine is $3,000.

Control everywhere else. Section 52 says the owner of any dog must keep it under control at all times. A dog found at large on someone else's land without their consent is treated as not under control, and failing to keep your dog under control is also a $200 infringement offence (maximum court fine $3,000).

Dangerous dogs. If your council classifies your dog as dangerous, the Act requires that within a month it is kept in a securely fenced part of your property that people don't have to enter to reach at least one door of the house (section 32). Some councils publish their own fencing standard for dangerous dogs. Kawerau District Council's, for example, sets a minimum height of 1.6 m, palings or rods no more than 50 mm apart, and gates that close and latch automatically. Menacing-dog classification brings a muzzle requirement and, if the council requires it, desexing, but the Act doesn't add a fencing rule. See our guide to banned and restricted dog breeds in NZ.

The Government announced a review of the Dog Control Act in March 2026, so check for changes. This guide reflects the Act as at September 2026.

Physical fences: what to check

SPCA NZ's advice for a new dog or puppy is to make sure it can't get under or over the fence, and to remove anything climbable near the fence. Auckland Council gives similar advice: no holes or gaps, tall enough that your dog can't jump over, and nothing like a compost bin or wood pile that it could climb to get over.

Practical points that follow from that advice:

• Walk the whole boundary, including behind sheds and along gates, looking for gaps and spots where a dog could dig under.
• Keep firewood, bins and outdoor furniture away from the fence line so they can't be used as a step.
• Use gates that close properly. Kawerau's dangerous-dog standard calls a self-closing, self-latching gate "critical", which is a sensible benchmark for any escape-prone dog.

Fences are not foolproof. In one NZ case reported by 1News in September 2026, dogs on a fenced property jumped the fence and bit a woman.

Electric, wireless and GPS "invisible" fences

These systems use a collar that, usually after a warning tone, delivers an electric shock or citronella spray when the dog approaches a boundary. The Code of Welfare: Dogs (MPI) describes the buried-wire type, and names "electronic boundary control devices" among training aids it classes as punishment-based.

They are not banned, but the Code sets conditions. Minimum Standard 19 says training aids, including electronic training devices, must not be used in a way that causes unreasonable or unnecessary pain or distress. The Code's recommended practice says electronic devices should be used carefully and only when other training methods have failed, should not be used on nervous dogs, and should not be left on unsupervised dogs, because they can cause serious harm if they malfunction or are activated accidentally.

Vets and SPCA advise against them. The NZ Veterinary Association says electronic boundary fences with no visible barrier should not be used to contain dogs. Its reasons: dogs in a high state of arousal can easily cross them, dogs receiving shocks can respond aggressively, and the invisible boundary makes it hard for a dog to link the shock to the boundary. SPCA NZ advocates a ban on the production, importation, sale or use of electric shock collars, including boundary-activated ones, and points to physical fencing and reward-based training as more humane alternatives.

Escapes are more common. A US survey of 1,053 dogs, published in the Journal of the American Veterinary Medical Association in 2017, found owners reported escapes for 44.0% of dogs contained by an electronic fence, compared with 23.3% behind a see-through or privacy fence and 26.8% on a tether. It was an owner survey, not a trial, and it didn't separate buried-wire from GPS systems; we found no published study of GPS fences for dogs.

Councils aren't consistent. Auckland Council's 2020 Responsible Dog Owner booklet said a sonic barrier "is not a good enough barrier" and that confinement means a fence, pen, cage, chain or similar, "not just a sonic barrier". Its current web page, however, lists a sonic barrier as one way to confine a dog. No law or court decision we found settles whether an electronic fence meets section 52A, so if you rely on one, check with your council.

Tethering is not a fence substitute

The Code of Welfare says dogs must not be contained or tethered in a way that causes injury or distress, and that prolonged containment or tethering can seriously affect a dog's physical and mental health. Its recommended practice is that if a property isn't appropriately fenced, the dog should be kept indoors or given an outdoor kennel with an attached run, or a tether. SPCA NZ advises against chaining or tethering except briefly when needed, for example while visitors are over or a fence is being repaired.

Since 25 September 2025 the Animal Welfare (Care and Procedures) Regulations also make it an offence to:

• tether a dog when two or more signs of prolonged tethering are evident, such as heavily worn ground, built-up faeces or a strong ammonia smell, a collar or tether that can't be released without tools, a tether injury, or signs of frustration like constant barking or pacing (infringement fee $500, court fine up to $1,500);
• tether a "vulnerable" dog on your own property, including a puppy under 6 months, a dog in heat, in late pregnancy or nursing (infringement fee $300, court fine up to $900).

Indoor gates and pens for puppies

For a new puppy, SPCA NZ suggests a play pen or baby gate, and keeping the puppy in one room for the first day or two, with warm bedding and a room that isn't cold. We couldn't find NZ guidance on gate sizes or types, so choose one your puppy can't squeeze through or climb.

Why containment matters

Auckland Council's 2024/25 animal management report recorded 16,739 complaints about roaming dogs and a record 10,214 dogs impounded, and it attributed much of a rise in attacks on people to more roaming dogs. Only 35% of impounded dogs were claimed by their owners. For council registration rules, see our dog registration guide. For safe places to exercise off the lead, try our off-leash dog areas finder.
