Deaths on New Zealand roads made up a "staggering" 41.7 per cent of all fatalities across Australasia over the holiday season, despite New Zealand making up only 15.2 per cent of the combined trans-tasman population.
Holiday road toll figures released by the Australia New Zealand Policing Advisory Agency (ANZPAA) yesterday put New Zealand's holiday toll at 20 - three higher than the official toll here - compared with Australia's toll of 28.
The discrepancy in the New Zealand toll was because the agency tracked deaths over a 12-day period from the beginning of December 23 until the end of January 3, while New Zealand officials counted fatalities between 4pm on Christmas Eve and 6am yesterday.
The Automobile Association's Dylan Thomsen described the agency's figures as "quite staggering".
"Considering Australia's population is so much larger than ours, that's quite a surprising figure," he said.
"Australia's had a better road safety record than New Zealand historically. They have a lower rate of road deaths and road crashes, but in the last two years and in 2013 in particular, we got down to where New Zealand was just about at the same rate of road deaths [as Australia]."
He pointed to Australia's "higher quality roads" and random road-side drug testing in some states as possible contributing factors in the country's better performance on the roads, but said it was not a fair comparison.
There were "differences in driving culture" that had to be taken into account.
"We have to acknowledge in New Zealand that we drive a lot as a nation, and people often are driving longer distances than in other countries - and over tougher terrain and lower quality roads - so you can't just look at other countries. It's not always an apples for apples comparison," Mr Thomsen said.
He said New Zealand had a "really unique set of circumstances", especially in rural areas where driving was often the only way for people to get around.
The AA would like to see a mandatory safety rating system for all cars sold in New Zealand, as well as the introduction of random road-side drug testing, Mr Thomsen said.
He also urged people to think about their driving behaviours, saying: "Everybody out there has something that they could do better when they're behind the wheel."
ANZPAA chief executive Jon White said this year's figures were "disappointing, if not downright tragic".
"It's certainly a disappointing upward tick in an overall downward trend, and certainly disproportionately higher fatalities in New Zealand than Australia."
However, it was not a long-term trend, he said, describing it as a "blip".
"From time to time this does happen, and indeed it's happened within Australia. South Australia, for example, if you look at the population ratio, they had a disproportionately higher number of fatalities within Australia, and like New Zealand they've been focussing very hard on the 'Fatal Five', the dominant things in crashes."
The 'Fatal Five' were drink-driving, speeding, distraction, fatigue and not wearing a seatbelt, he said.
Mr White urged drivers to focus on cutting out these "avoidable" factors.
Early indications were that alcohol and speeding were factors in at least eight of New Zealand's holiday fatalities, road policing Assistant Commissioner Dave Cliff said today.
"It is a bad decision to drive after drinking. It's that simple."
The official holiday road toll from New Zealand authorities is 17, compared with seven last year, when the official holiday period was three days shorter.
Last Year's ANZPAA figures put New Zealand's road toll at eight out of a total of 36 across both countries - making up 22.2 per cent of the total figure.
