Waikato and Bay of Plenty state highway works for May 2023


Waka Kotahi contractors will continue working throughout the winter months as ongoing wet weather is having a significant impact on the state highway network across New Zealand, including in the Bay of Plenty region.

During the wet winter months contractors will focus on completing minor repairs to maintain the integrity of the road before more permanent repairs can be completed in the warmer months. 

As well as this, contractors are continually monitoring the network and proactively managing isolated issues as they appear, says Roger Brady, Bay of Plenty System Manager, Maintenance and Operations. 

“We have a regular process to inspect the state highway network across the Bay of Plenty region, and this allows us to respond quickly to issues as they appear on the network. 

“During the colder months we need to deal with ice in some areas. Our key weapon against ice on the roads is calcium magnesium acetate (CMA), sometimes mixed with grit. This substance lowers the temperature at which water on the road surface freezes. We apply this based on local knowledge of hazard spots, and thermal mapping. The thermal mapping process uses data from strategically placed remote-reporting weather stations to predict where icing is likely to occur on the network.  

“As always, it is important to drive to the conditions, and we encourage road users to slow down in areas we have applied CMA and/or grit. 

“Finally, there will be times when we are unaware of issues on the extensive Bay of Plenty network, such as individual potholes, isolated flooding or slips. If you come across these type of issues we encourage you to advise us via 0800 4 HIGHWAYS (0800 44 44 49) so we can respond as quickly as possible.” 

Road users are always reminded to check the Journey Planner (www.journeys.nzta.govt.nz(external link)) for up-to-date road conditions across the state highway network.
