Speed limits on the most dangerous roads could drop to 80km per hour as the government seeks to combat the high number of road deaths.
Associate Transport Minister Julie Anne Genter says the government's Vision Zero road safety plan seeks to drop the number of road deaths by half in the next decade.
One way to do that will be by reducing the speed limit on some roads, and the New Zealand Transport Agency (NZTA) is already working to identify which roads should have lower speed limits.
"In the government policy statement, we identified rolling out the safe and appropriate speeds as identified in the speed management guide," Julie Anne says.
"We wouldn't have a blanket reduction. What is important is that we're going to focus on the most dangerous roads, revising them to have a safe and appropriate speed limit, and making it easier for local councils to get a safe and appropriate speed limit.
"At the moment, they have to go through a lot of bureaucratic hoops to get the speed limit changed. It should be easy, straightforward, and quick to change it to an appropriate speed limit."
Julie Anne spoke to RNZ about the international Road Safety Week which begins today, and discussed ways the government hopes to make roads safer.
She says roads will be improved with better safety features.
"We're already making progress on this in terms of investing in cost effective safety upgrades right around the country," Julie Anne says.
"We have the $1.4 billion work programme, which is all about median barriers, side barriers, wider shoulders, wider centre lines, rumble strips, all things which are proven to reduce fatal and serious injury crashes.
"That will cover thousands of kilometres of our road network over the next three years."
But Julie Anne says it is "no secret that many of the posted speed limits are not a safe speed limit to travel at" on New Zealand roads.

As of last night, 144 people had died on the roads this year, a number that is tracking higher than the 377 who died on the road last year.
Asked if lowering speed limits would be a brave move, Julie Anne says people will understand.
"I have a slightly different view. I actually think there are lots of New Zealanders and a lot of visitors to New Zealand who are driving around on our roads who would be much happier with a more appropriate speed limit," she says.
"It's actually less stressful to drive on a road when you're able to travel at a safe speed limit and not be under pressure to travel at a faster speed.
"There will be a percentage of the population, a minority, who aren't happy with this. But I actually think there'll be a silent majority who are quite in favour and say, actually, it's the right thing to do."
Julie Anne says the NZTA is reviewing the speed limit on many roads, and has already signed off on a number of speed limit reviews.
She says it would only be on the "most dangerous roads where it is going to save lives".
