Roads in Northland have been affected by Cyclone Vaianu’s heavy rains and gale-force winds.

The New Zealand Transport Agency Waka Kotahi (NZTA) said the severe weather has impacted state highways, with crews responding to various issues such as fallen trees, damaged streetlights on the road, debris, flooding and minor slips.

NZTA said State Highway 1 on the Brynderwyn Hills is open but under stop/go traffic management because of various small slips encroaching into the southbound lane.

“Crews are on site clearing what they can, but some work will need to wait until the conditions improve,” a spokeswoman said.

The slips are near Artillery Rd and near the SH12 intersection.

SH1 in Mata is open but the NZTA urged drivers to take care because of surface flooding between Salmon Rd and Flyger Rd.

SH15 is closed between Cemetery and Loop roads because of flooding, with a detour available via SH1.

Far North

Far North Mayor Moko Tepania said no local roads had been impacted by Cyclone Vaianu, however, some were damaged from another recent storm, along with 99 local roads from March 25 and 26 weather events.

“So there’s a lot of recovery work which needs to go on but from Cyclone Vaianu, not anything major.”

A slip on Rawene’s Parnell St appears to have burst a water main, according to Kaikohe-Hokianga Community Board chairwoman, Jessie McVeagh.

The slip occurred in previous flooding but appears to have got worse overnight, and some Hokianga residents have reported a drop in water pressure this morning.

McVeagh put cones on the slip this morning and has ensured Far North District Council knows the situation is urgent.
