Waka Kotahi, New Zealand Transport Agency's spring / summer road maintenance programme, will see about 100km of state highway in Northland resealed, including areas in Warkworth.

Resealing in Warkworth starts this month and ramps up in October as the days become longer and warmer. Sections will be resealed near the Hudson Rd intersection, which will be done at night to minimise disruption to traffic, and new asphalt will be laid on SH1 to the south of Warkworth.

The warmer weather helps the new seal stick to the road surface. Weather conditions are critical, as was demonstrated earlier this year. 

In November and December there will be new chip seal on sections of SH1 between Kawakawa and Warkworth. While this work will be largely done at night, motorists may experience some daytime delays.

"This year we will be implementing more short-term and cost-effective repair solutions such as pothole repairs and localised patching work, rather than more significant maintenance improvements. This should result in less disruption on the network for motorists," said Northland system manager, Jacqui Hori-Hoult.

Despite the significant roadworks programme, most work will stop before busy holiday travel periods like Labour weekend, Christmas and New Year, to minimise disruption to people's journeys.

Hori-Hoult said the repairs and resurfacing would keep the road surface maintained and make it safer, but everyone had a responsibility for safety while the work is being done.

"We ask all motorists to do their bit by slowing down and keeping to the temporary speed limits. The speed limit applies on both sides of the road, even though work may only be occurring in one lane at a time. Driving at the posted speed limits helps bed in the new seal and prevents stone chips flying into windscreens," she said.

"The road crews will do their bit by working hard to minimise inconvenience and delays. We urge people to be patient, plan their journeys and allow extra time."
