NZ review of the Kurgo Enhanced Strength Tru-Fit car harness — sizing for NZ breeds, buckle concerns, and how it compares to the EzyDog Drive.
Māui’s first car harness was a generic nylon thing from a pet shop bargain bin. It worked — right up until it didn’t, and I realised the buckle was the only thing stopping him from becoming a 28kg projectile on the motorway. I replaced it with a proper crash-tested harness that same week.
The Kurgo Enhanced Strength Tru-Fit is one of the cheapest crash-tested harnesses on the NZ market — and if you’ve done the reading and decided a harness (not a crate, not a booster) is what you want for your dog, it’s a legitimate pick. This is the honest review: what it does well, where it falls short, and who should actually buy it.

The short version
- Crash-tested? Yes — 48km/h frontal Calspan sled test (FMVSS 213, manufacturer-commissioned). Not CPS-certified.
- Price: roughly $50–110 NZD (size and retailer dependent). Kurgo’s AU site (which ships to NZ) is usually cheapest; NZ retailers sit in the $85–110 range.
- Sizes: XS to XL, fitting dogs 2–50kg (crash-tested up to ~34kg).
- Best for: Medium dogs (11–34kg, i.e. sizes M and L) whose owners want genuine sled-tested safety without spending EzyDog or Sleepypod money.
- Main weakness: Standard plastic buckles — a small number of NZ owners flag buckle quality as the weak point.
If you want the short answer: it’s the right harness for most dogs, most of the time. If you want the detail, read on.
What “crash-tested” means for this specific harness
“Crash-tested” is a phrase manufacturers use loosely. There are two distinct things worth knowing about the Tru-Fit, and most of the online write-ups blur them.
What it passed: the redesigned v.3 Tru-Fit (2018 onwards) was tested by Calspan — the US lab that runs NHTSA vehicle crash work — against FMVSS 213, the US child restraint standard adapted for a canine dummy. A 48km/h frontal impact, weighted dummy, independent lab, results published. It passed. That’s a manufacturer-commissioned test, not third-party certification, but it’s a real sled test at a real lab — well ahead of the “built strong” harnesses with no independent data.
What it isn’t: CPS-certified. The Centre for Pet Safety runs its own certification programme (CPS-001), and the only harnesses that currently hold CPS certification are Sleepypod’s Clickit range. The original pre-2018 Tru-Fit was tested by CPS in 2013 and failed; Kurgo redesigned it in response. CPS has not publicly retested the current v.3.
Worth noting: Kurgo’s own Calspan test was conducted on dogs up to ~34kg (75 lbs). XL dogs above that weight are within the harness’s fit range but outside the crash-tested envelope.
For context: if a harness doesn’t mention Calspan, CPS, ADAC (the German equivalent), or a specific independent test, assume it’s untested. Most of the market is untested. The Tru-Fit isn’t — just be clear on exactly which standard it’s passed.
For the full category context, see the best crash-tested dog car harness in NZ guide — it compares the Tru-Fit directly with the Sleepypod Clickit and EzyDog Drive.
Build and fit
The Tru-Fit is a webbing-and-pad harness with five adjustment points: two at the neck, two at the chest, and one at the belly. That’s more adjustment than the EzyDog Drive’s three-point system, and it matters if your dog is an awkward shape — deep-chested Staffies, skinny Greyhounds, barrel-chested French Bulldogs, anything that doesn’t fit the generic-retriever build.
Padding sits along the chest plate where the crash load concentrates. It’s not luxurious padding — the harness is built for safety, not sofa comfort — but it’s enough that a dog can wear it for a two-hour drive without rubbing. Māui wore a size L on trips to the Kāpiti coast without any chafe marks.
Two attachment points on the back: a steel D-ring for lead attachment (yes, you can walk the dog in it, though it’s not the most comfortable walking harness), and a seatbelt loop for car use. The seatbelt loop is the critical bit — the car’s existing seatbelt threads through it, so the crash load transfers to the vehicle’s belt system rather than relying on a separate tether.
NZ sizing quick guide
The manufacturer weight brackets aren’t a bad starting point, but chest girth is what actually matters. Measure just behind the front legs with a soft tape.
- XS (30–46cm girth): Chihuahuas, Toy Poodles, Papillons
- S (41–56cm girth): Jack Russells, Cavoodles, Miniature Schnauzers
- M (46–71cm girth): Spaniels, Border Collies, medium Staffies, Whippets
- L (61–86cm girth): Labradors, Golden Retrievers, larger Staffies, German Shepherds on the smaller side
- XL (71–112cm girth): Large GSDs, Rottweilers, Great Danes
If your dog is between sizes, size up. A slightly loose harness is easier to adjust than a tight one that restricts breathing.
Installation — what actually happens
Getting the harness on a dog that hasn’t worn one before is the usual pantomime: over the head, front legs through the chest loops, clip the belly strap, adjust everything that now looks wrong. The first fitting takes five minutes. Every subsequent one takes about thirty seconds.
In the car, the seatbelt threads through the loop on the back of the harness. Click the belt in as normal. The dog now has enough slack to sit, lie down, or turn around — but not enough to climb into the front seat or launch off the seat in a sudden stop.
The instruction sheet is useless. Watch the Kurgo fitting video on YouTube instead — it’s two minutes and clearer than the diagrams.
The buckle concern — addressed honestly
There’s a persistent thread in NZ reviews (Animates, Petdirect, independent forums) noting the buckles. The harness uses standard plastic side-release buckles, the same type you’d find on a backpack sternum strap. They’re rated for normal load but a small number of owners have reported them feeling loose over time, and a handful have reported buckle failure.
Here’s the honest context:
The load path in a crash runs through the webbing loop attached to the seatbelt — not through the buckles. The buckles are there to let you get the harness on and off the dog, not to restrain crash forces. Even if a buckle failed during normal driving, the seatbelt loop would keep the dog attached to the car. In a crash itself, the buckles aren’t structural.
That said: inspect them. If a buckle cracks, looks chalky, or the side-release feels notchy, replace the harness. At ~$50–110 NZD it’s not a lifetime product — think of it as a 3–5 year item for a dog that rides frequently.
The EzyDog Drive uses metal hardware for the main load-bearing attachment, which is a point in its favour if the buckle issue makes you twitchy. But most NZ owners have run the Tru-Fit for years without a problem.
How it compares to the EzyDog Drive
The EzyDog Drive is the main NZ competitor. Both are crash-tested. Both use a seatbelt loop-through. Both are widely stocked. The differences:
- Price: Tru-Fit ~$50–110, Drive ~$100–150. Tru-Fit wins on value.
- Build: The Drive has a rigid moulded chest plate; the Tru-Fit is webbing and padding. The Drive feels more substantial. The Tru-Fit is easier to clean and pack.
- Sizing flexibility: Tru-Fit’s five adjustment points handle awkward builds better. The Drive’s rigid plate is better for proportional dogs.
- Crash rating: Both manufacturers commission independent sled tests; neither is CPS-certified. The only CPS 5-star harnesses are Sleepypod’s Clickit range.
- Use as walking harness: Neither is designed for it. If you want one harness for walks and car trips, see the general best dog harness in NZ guide — you’re better off buying two purpose-built ones.
If the harness lives in the car and gets used three or four times a week, the Tru-Fit is the sensible buy. If your dog is in the car daily, or you live rurally and racks up hours on the road, the Drive’s sturdier build is worth the extra $20–30.
Who it’s for
Buy the Tru-Fit if:
- You have an 11–34kg dog (sizes M or L — the crash-tested range) that rides in the car regularly but not daily
- You’ve decided on a harness (not a crate or booster) for restraint
- You want proper crash-testing without paying $250+ for a Sleepypod
- You don’t mind checking the buckles before each trip
Look elsewhere if:
- Your dog is under 5kg — consider a booster seat or secure carrier instead
- Your dog is a very strong chewer who destroys webbing — the Tru-Fit is crash-rated but not chew-rated
- You want a harness that doubles as a no-pull walking harness — the Tru-Fit isn’t designed for that
- You’re after the absolute highest safety rating and budget isn’t a constraint — Sleepypod’s Clickit range is the CPS 5-star choice

Bottom line
The Kurgo Enhanced Strength Tru-Fit is the right car harness for most NZ dog owners. It’s genuinely crash-tested, it fits most dogs well, and it costs less than a vet bill from an unrestrained dog emergency.
The buckles are the one weak point. Inspect them, replace the harness if anything looks cracked, and the rest of the harness will outlast most dogs’ patience for wearing it.
If you want the absolute safest option and money’s no object, Sleepypod’s Clickit range holds the CPS 5-star ratings. If you want a sturdier feel and wide NZ pet-store stock, the EzyDog Drive is the call. For everyone else — which is most people — the Tru-Fit is the honest, sensible answer.
Pair it with a proper seat cover or hammock to protect the upholstery, and you’ve got a setup that’ll survive most of what NZ roads can throw at you.
Restrain your dog. Cabin restraint isn’t legally required in NZ (ute-tray transport is — Animal Welfare Regulations 2018), but it should be for both.
