While South Island highways affected by snow and flooding earlier today have reopened, North Otago’s rivers are rising and very likely to cause highway closures overnight.

SH1 near Seddon in Marlborough reopened to single lane just after 3 pm. People should build in extra time if they are using SH1 until the flood waters fully recede, says Tresca Forrester, Journey Manager, Waka Kotahi.

Most other routes require care particularly heading into the night, she says. Across the network, damage from recent storms may not be easily visible so drivers are reminded to build in extra time and drive to the conditions.

North Otago new focus

Rain is continuing to fall steadily with some Coastal North Otago highways requiring extreme care as flooding increases and rivers and creeks rise. 

Graeme Hall, System Manager for Waka Kotahi in Otago, says SH1 is likely to close in coming hours north of Maheno at Kakanui River and north of Hampden at Big Kuri Creek.

There are no detours available so drivers may need to postpone their journeys. The flooding that is causing these two closures/flooding is expected to continue overnight until at least 9am Wednesday.
