A police officer of 17 years says this week has been the worst of his career to date, with 14 deaths on the country's roads in just five days.
The number of road fatalities in New Zealand is emerging as one of the nation's biggest problems, national manager for road policing Superintendent Steve Greally told NZ Newswire on Wednesday.
Speed was the top factor when it came to crashes, and Supt Greally said limits needed to be reviewed to reflect the state of roads.
"We can put 110km/h on roads built for it, like expressways, but the reverse is equally true. If we increase speed on those, we need to decrease speed on those not engineered for high speeds," he said.
The latest fatal crash, north of Taupo, killed four people - including a five- year-old boy - and injured a further eight on Tuesday.
