The speed limit on State Highway 1 through Kaiwaka is to be reduced from 100km/h to 60km/h in an effort to increase safety for residents and road users.
The New Zealand Transport Agency said it was introducing more consistent speed limits, which means there will be lower limits over a greater stretch of the highway.
"By introducing just one speed limit that is clearly signposted and doesn't change partway through the township, it's anticipated that motorists will understand what's expected of them and are more likely to drive within the limits," agency system design manager Brett Gliddon said.
