The rule allowed for lower speeds to be kept on rural connectors and interregional connectors if the majority of road users and local communities supported retaining lower speeds, said the roading agency.
“In light of this change, NZTA will continue to assess the safety of the state highway corridor including at intersections, balancing the considerations of local residents with the safety of all SH2 road users.”
When SH2 reverts to 100km/h, the speed limit for heavy vehicles and towing vehicles will be 90km/h.
The speed limit for State Highway 2 was changed after a 2019 public consultation by NZ Transport Agency Waka Kotahi (NZTA), when there was a significant public push to make the highway safer, including a public protest, NZTA media manager Natasha Utting said in an email.
“In December 2020, the speed was lowered from 100km/h to 80km/h between Katikati and Te Puna as it was one of the highest-risk roads in the country.”
“This stretch of SH2 has undergone safety improvements since then, including road widening, wide centre lines, intersection improvements and median and side barrier sections,” Utting said.
In the 10 years before the speed reduction, 18 fatal crashes and 46 serious injury crashes occurred, according to NZTA.
State Highway 2 was once a rural road that passed through a few settlements and had since developed into a commuter and freight route, Utting said.
“This increasingly busy road currently has around 15,000 vehicles travelling through Katikati and increasing to more than 20,000 vehicles a day further east to Te Puna, with many intersections and driveways with direct access on to SH2.”
