Waka Kotahi NZTA Wellington/Top of the South regional manager Mark Owen said the rain has caused flooding this morning on State Highway 2 through Hutt Valley and on SH1 in central Wellington near the Basin Reserve.
“There has also been a southbound lane closure on State Highway 59 near the Mungavin interchange due to a fallen tree and reports of minor slips and rockfalls on other parts of the local state highway network.”
A police spokesperson said cordons had been put in place in Porirua and motorists heading south should take alternative routes where possible.
The spokesperson said it was unclear how long it would take to clear the fallen tree.
A slip has also blocked an area of SH2 north of the Melling interchange at Lower Hutt.
It has caused traffic to back up and motorists were being asked to use different routes.
Contractors were working hard to keep roads open, but drivers were encouraged to check road conditions before they travelled, Owen said.
The bad weather meant drivers must be prepared for hazardous driving conditions.
“If visibility is bad, make sure your headlights are on so that other drivers can see you. Watch your following distances and expect the unexpected. Remember, it is better to arrive late than to not arrive at all.”
