Flood clearing in Plimmerton over the weekend could increase after heavy rain.

The landslide damaged two houses in Porirua as heavy rain continues to fall across the Wellington region.

One home has been evacuated and another is likely to follow a landslide on Moonsail Drive, Whitby, just after 9pm on Monday, a spokesman for the fire and emergency services said.

A heavy rain warning remains in place in the region, with a 50-60mm drop forecast overnight.

The warning is in effect for Wellington and the Kapiti Coast, south of Ōtaki, until 1 a.m., and a strong wind warning is in the same area until 10 a.m. Tuesday.

FENZ received 10 calls related to the 6 p.m. floods, in Tawa, Plimmerton and areas in the Hutt Valley.

MetService expects that heavy rain could cause rapid growth of streams and rivers, and surface floods and slips are possible, and driving conditions can potentially become dangerous.

Between 7pm and 9pm on Monday, MetService data showed Wainuiomata experienced 27.6mm of rain, Lower Hutt, 20.2mm, Upper Hutt, 19.2mm, Central Wellington, 15.4mm and Porirua, 7, 2 mm.

The New Zealand Transport Agency is asking drivers to slow down and increase distances due to flooding on State Highway 1 in Ngauranga Gorge, SH1 from Plimmerton to Pukerua Bay and SH2 from Petone to the Haywards exchange.

The south branch of SH1 Johnsonville was previously closed due to flooding, but has since reopened.

The pedestrian was transferred to the hospital in a moderate condition after he ran into a motorcycle on the Terrace, between Bolton St and Aurora Tce, which in the meantime reopened after it was temporarily closed.

After heavy rain on Sunday, the roundabout on State Highway 1 near Plimmerton was closed due to flooding. The NZTA said there was a risk that a similar flood could happen again tonight.

The Wellington Grand Regional Council said Sunday’s flood in Plimmerton was a flood of one in 10 years.

It recorded 51mm of rain at Whenu Tapu Cemetery in Plimmerton, the third three-hour total since 1991.

At Battle Hill Farm, three-hour rains totaling 59 mm were recorded.

“The rain there was very intense during the period, with a 20mm drop in just 20 minutes,” a GWRC spokesman said.

Further north near Te Horo and Ōtaki, 50 mm-60 mm of rain was recorded over six hours, which also caused some flooding, estimated at a seven-year event.

The Kapiti-Man Red Cross Disaster Response Team was activated today in Plimmerton and is providing field support to residents of the affected areas.

Poriru City Council said 20 trucks of mud had been cleared on Monday in preparation for further rain.

A council spokeswoman said 15 homes were considered uninhabitable and was helping two families in emergency accommodation. Others agreed on their own.

NZTA Regional Transport Systems Manager Mark Owen said there is again a risk of water accumulation around the Plimmerton roundabout and on State Highway 2 around Petone.

The tide in Porirui is expected on Monday at 11 p.m.
