The best crash-tested dog car harnesses in New Zealand — Kurgo Tru-Fit, EzyDog Drive, and Sleepypod Clickit compared. NZ pricing, sizing, whether you need a tether.
Last updated
By Jess Aldridge Māui spent the first two years of his life as a free-range passenger. Then one afternoon I had to brake hard on the Ngauranga on-ramp, and 28kg of staffy slid off the back seat into the footwell, hit the back of the passenger seat on the way down, and gave me a look that translated roughly as “why.”
He was fine. The next week I bought a proper harness.
An unrestrained dog in the car is a distraction at best and a projectile at worst. At 50km/h, a 25kg dog hits with roughly 750kg of force. You don’t get to argue with physics, and most dog car harnesses sold in NZ — including some that say “safety” on the label — have never been crash-tested at all.
This guide is narrow on purpose. Only harnesses that have actually been tested against a published crash standard. No marketing fluff, no “built strong” claims without a certificate behind them.
Best overall: Kurgo Enhanced Strength Tru-Fit — independently crash-tested, five sizes, widely stocked, sensible price
Best premium pick: Sleepypod Clickit Sport — the only harness with a 5-star CPS result, but you pay for it
Best in-store pick: EzyDog Drive — Australian-designed, crash-tested, stocked everywhere
Best accessory add-on: Kurgo Direct to Seat Belt Tether — short restraint for harnesses without a built-in loop

“Crash-tested” is one of those phrases that sounds official but isn’t regulated. Any manufacturer can say their product is “tested for safety.” Far fewer can point to an independent test result against a published protocol.
The one that matters is the Centre for Pet Safety (CPS) standard. CPS is a US non-profit that developed the closest thing the pet-product industry has to a crash-test standard — modelled on the FMVSS 213 protocol used for child car seats. A harness gets strapped to a weighted canine test dummy, put through a 48km/h (30mph) frontal crash simulation, and scored on:
The scoring goes up to five stars. A CPS-certified harness is the closest thing to an honest safety claim you can buy. Anything without a CPS result (or a comparable independent test like ADAC in Germany) is guessing.
Three harnesses in NZ-reachable markets have meaningful CPS results. Those are the three below.
NZ has no cabin-restraint law for dogs. The Animal Welfare (Care and Procedures) Regulations 2018 require dogs on open ute trays to be tethered so they can’t fall or be thrown off. Inside the cabin? Nothing specific.
What the law does cover:
So you’re not going to get ticketed for an unrestrained dog on the Northern Motorway. But if that dog causes a crash, or ends up hurt in one, you’ll wish you’d spent the $60.
Vest-style harnesses (chest-plate design)
A rigid or semi-rigid chest plate distributes crash forces across the sternum and ribcage — the strongest part of the dog’s skeleton. The Kurgo Tru-Fit and EzyDog Drive both use this pattern. It’s the most common crash-tested design and the one most dogs tolerate well.
Full-torso restraint harnesses
More structural webbing, more contact points, typically heavier. The Sleepypod Clickit Sport is the stand-out example — it uses three points of attachment and looks closer to a child-safety harness than a dog harness. Higher protection, more fuss to put on.
Seatbelt-clip harnesses without crash testing
Lots of these on the market. Avoid for safety use. Fine as a walking harness with a convenient car clip, but don’t confuse them with genuine crash gear.
The Tru-Fit is Kurgo’s flagship car harness and the one I’d recommend to most NZ dog owners. It uses the standard chest-plate design — a padded front panel connected by five adjustment points so you can fit it genuinely snug without pinching. The crash protection comes from the steel nesting buckle at the chest and the reinforced stitching on the seatbelt loop.
The built-in seatbelt loop is the key feature. You thread your car’s seatbelt through the loop on the back of the harness, click in as normal, and the dog is anchored to the same system that anchors you. No separate tether needed for most setups.
Size range matters here. Kurgo goes XS to XL, which means a Cavoodle and a Ridgeback can both use the same product line. A lot of crash-tested harnesses only cover medium-to-large dogs — the Tru-Fit is one of the few that genuinely fits a 5kg dog safely.
Who it’s for: Most NZ dog owners. This is the right answer unless you’ve got a specific reason to spend more.
The honest caveat: There’s a NZ review thread on the Animates site flagging buckle concerns — a handful of owners reporting the chest buckle cracked after heavy use. Kurgo has iterated the design at least once since those reviews and the current “Enhanced Strength” version uses a revised buckle. If it’s still a concern, inspect the buckle monthly and replace at the first sign of stress marks. Not a reason to avoid the harness, but worth knowing.
The Clickit Sport is the harness you buy when the science matters more than the price. It’s the only harness tested by CPS that has received a five-star rating across multiple weight classes — the closest thing to a “safest” claim the industry has.
The design is different. Instead of a chest plate, the Clickit uses a full-torso vest with three points of webbing attachment: chest, back, and a third point that anchors to the car’s seatbelt. In a crash, force spreads across the entire torso rather than concentrating at the chest plate.
The trade-offs are real. It’s more fuss to put on than a Tru-Fit — more straps to adjust, and most dogs need a bit of training to tolerate the snugger fit. NZ availability is thin. You’re typically importing it, which adds freight and duty. And for daily use as a walking harness, it’s more harness than most people need.
Who it’s for: Owners of larger dogs (15kg+) who are safety-motivated enough to pay double and deal with the import. Also a reasonable pick if your dog has been in a prior crash and you want the highest-rated option on the market.
Go with the Kurgo instead if: Your dog is under 10kg (Sleepypod sizing skews larger), or you don’t want to deal with import logistics.
EzyDog is the Australian-owned brand you’ve seen on the wall at every Animates. The Drive Harness is their crash-tested option — independently tested to ECE Regulation 21 (European vehicle interior fittings standard), which isn’t the CPS standard but is a comparable independent protocol.
The design is similar to the Kurgo: chest plate up front, seatbelt loop at the back. What you’re paying for is the NZ/AU support infrastructure. Sizing is handled at Animates stores, returns are easy, and you can walk into a shop and have a staff member fit it to your dog. That counts for something, especially if you’re not confident measuring chest girth yourself.
Build quality is genuinely good. I used one for Māui for about 18 months before switching to the Kurgo on price grounds — they’re comparable in use, but you’re paying an NZ/AU premium for the local brand and stocking footprint.
Who it’s for: Owners who want the easy buy-in-store, fit-in-store experience and don’t mind paying for it. Also the right pick if you already own other EzyDog gear and want to pair with the EzyDog Click seatbelt attachment.
Go with the Kurgo instead if: You’re price-sensitive and comfortable fitting the harness yourself.
Short answer: usually not, if your harness has a built-in seatbelt loop.
A tether is a separate strap that connects a harness D-ring to an anchor point in the car (seatbelt, LATCH, or zip-line). For the full breakdown of each tether type and when to use them, see the dog car tethers guide for NZ. You’d use one if:
For the Kurgo Tru-Fit and EzyDog Drive, the built-in loop handles this. Thread the seatbelt through, click in, done. Kurgo sells a Direct to Seat Belt Tether at ~$32–35 NZD if you want a separate shorter restraint, but it’s an accessory, not a requirement.
Where a tether is worth adding: if you have a genuinely restless dog and want to cut down how much they can shift around mid-trip. A short tether paired with a crash-tested harness gives you belt-and-braces. But for the average dog, the built-in loop on the Tru-Fit is enough.
A rough starting point. Always measure chest girth before buying — deep-chested and barrel-chested breeds don’t match weight-based sizing.
| Dog weight | Kurgo Tru-Fit size | EzyDog Drive size | Notes |
|---|---|---|---|
| 3–8 kg | XS | XS | Chihuahua, Toy Poodle, small Cavoodle |
| 8–15 kg | S | S | Mini Schnauzer, Cocker Spaniel, Cavoodle |

Any harness that doesn’t publish a crash-test result. “Tested for strength” or “rated to 45kg” is not a crash test. Ask for the standard — CPS, ECE R17, or ADAC. If there isn’t one, it’s a walking harness with a clip.
Seatbelt clips that attach to a collar. Sudden-stop forces on a collar will strangle or break the neck of a dog. Chest harness only. Always.
Extender straps sold as “crash restraints.” These are loops of nylon webbing that turn a walking harness into a “car harness” by letting you thread the seatbelt through. They don’t change the crash performance of the walking harness they’re attached to.
For most NZ dog owners, get the Kurgo Enhanced Strength Tru-Fit. Independently crash-tested, fits dogs from 3kg to 50kg+, and costs about half of what the premium options charge.
If you want the highest-rated harness on the market and don’t mind importing, go with the Sleepypod Clickit Sport. It’s the only 5-star CPS result.
If you’d rather buy in-store and want NZ-brand support, the EzyDog Drive is a solid choice — just be aware you’re paying a premium over the Kurgo for comparable protection.
Whichever you choose, measure the chest girth first, check the seatbelt loop threads through your car’s belt cleanly, and inspect the harness hardware every few months. Crash-tested only counts the first time it’s crashed — after that, replace it.
The gear is cheap relative to a vet bill or a dead dog. Restrain your dog properly. It’s not a legal requirement in NZ, but it should be.

It means the harness has been tested against a standardised protocol — usually the Centre for Pet Safety (CPS) standard, which simulates a 48km/h frontal crash with a weighted canine test dummy and scores up to five stars. Many harnesses claim crash protection without any independent testing. 'Crash-tested' only counts when it's tied to a published standard and a passing result.
There's no specific NZ law requiring dogs to be restrained inside a vehicle. The Animal Welfare (Care and Procedures) Regulations 2018 cover ute trays (tethering required) but not the cabin. That said, a loose dog that distracts the driver can lead to a careless driving charge, and the physics of an unrestrained dog in a crash are ugly regardless of the law.
Most crash-tested harnesses include a seatbelt loop so you don't need a separate tether — you just thread the car's seatbelt through the harness. Tethers come in when the harness you own doesn't have a seatbelt loop, or when you want to anchor to a LATCH point instead. For the Kurgo Tru-Fit and EzyDog Drive, the built-in loop is enough.
Measure your dog's chest girth just behind the front legs — that's the number manufacturers size against. Don't guess from weight alone, especially for deep-chested breeds like Staffies or Greyhounds. All three harnesses below publish size charts; take the measurement first, then match.
You can, but it's not designed for crash forces. A walking harness has stress points in the wrong places and the hardware isn't rated for impact loads. In a crash it can fail or injure your dog. If you're going to restrain the dog, use the right gear.
