Motorists and residents in Kaipara can now consult an online mapping tool to see the status of repairs to the hundreds of slips affecting the council-maintained roading network, following severe weather events in 2022-2023.
Coloured pins on the map, which covers the three Northland district councils (Kaipara, Far North and Whangārei), show which repairs have been completed (green), which need repairs costing under $100,000 (blue), and which require more complex repairs, costing more than $100,000 (red).
Clicking on a pin brings up relevant information about the problem area. A red pin on the Mangawhai-Kaiwaka Road, for example, shows that an underslip affecting 60 metres of road is set to be repaired using an engineered wall – a project that is in the planning stage, with construction expected in the July-September quarter.
Three other red pins in the wider Mangawhai area indicate slips on Lawrence Road, on Mangawhai Road (between Avocado Road and Paul Lane), and on Mangawhai Road (between Carter Road and Wood Pigeon Lane).
According to KDC general manager for infrastructure Anin Nama, council-administered roads in Northland sustained about $89 million worth of damage from at least 10 significant weather events since July 2022, and damage worth $34 million occurred in Kaipara alone.
Of 195 remaining slips in the three districts, just under one-third were in Kaipara, and Nama says it may take another year or more for some of the repairs to begin.
“We have restored most roads but are still working on 57 sites in the Kaipara,” he says. “To some motorists, it may seem like very little is happening to address these remaining slips. That is not the case. Some of these sites are very complex, with significant engineering, planning and funding questions that must be resolved before contractors can start working on repairs.”
The road slips map was created by the three councils and uses data provided by the Northland Transportation Alliance (NTA), a collaboration of Northland local governments and Waka Kotahi NZTA. Find the map at: https://www.kaipara.govt.nz/northland-slip-repair-map
