• SH1 Hikurangi (trees down on road - detour via the Hikurangi Bypass)

Restrictions, with one-lane open at:

• SH1 Mangamuka Gorge (slips and tree branches on road)

11:10am: Better news out of Westport, with officials telling those who evacuated their homes last night they are able to return today during a "lull" in the weather.

However, they have been warned they may need to evacuate again should conditions worsen there.

11am: Wild seas have seen a boat smashed against the rocks on Auckland's Tamaki Drive this morning.

Vector has also given an update for Auckland power customers: "Heavy rain and strong winds struck Tāmaki Makaurau Auckland overnight causing a small number of outages, particularly in the city’s western fringes.

"The majority of the outages are weather-related faults, such as trees falling on power lines, but the overall impact on the network has been minimal.

"While more rain is forecast, winds are expected to level off during the day, allowing our crews to restore power safely and as quickly as possible to those still impacted."

10:30am: A reminder it isn't just the top of the South Island and West Coast doing it tough.

10.18am: MetService has updated its severe weather warnings.

Red heavy rain warnings remain in place in Buller (12 hours from 9am Thursday), Nelson district (14 hours from 9am) and Westland (13 hours from 9am). In all three regions, rain is expected to return on Friday afternoon and ease Saturday afternoon.

There are orange heavy rain warnings in Northland, Auckland including Great Barrier Island, Bay of Plenty west of Edgecumbe, Waikato south of Raglan, Waitomo and Taumarunui, north Taranaki away from the mountain, Tongariro National Park, Mt Taranaki, Tasman west of Motueka, the Tararua Ranges, Marlborough Sounds, Rai Valley and Richmond Ranges.

There is an orange strong wind warning in Northland.

9.34am: Nelson Tasman Civil Defence says boil water notices are only in place for Eighty Eight Valley and Dovedale, not Nelson.

Nelson water is safe to drink.

9.13am: Buller Civil Defence says bunds, pumps and sandbags have so far helped to mitigate the impact of the severe weather.

Of the 160 Westport households encouraged to self-evacuate, most stayed with family and friends. Four people were placed in motels and another spent the night in an evacuation centre.

"It's tempting to think that it's all over but there is a second weather front due to affect Buller District tomorrow night and into Saturday, so we won't be dismantling all our protective measures yet," controller Al Lawn said.

Checks on critical infrastructure are underway and 5000 more sandbags will be arriving in Westport.

The West Coast remains under a state of emergency and a red weather warning is still in place.

8.50am: Buller Emergency Management says river levels are going down and surface flooding seems to have reduced.

"Te Kuha hit its first alarm in the early hours of the morning but we are watching it decrease. Karamea and Mokihinui levels are also dropping," it said on Facebook.

It said high tide this afternoon is one of its considerations before it gives the message for anyone evacuated to return home.

8.40am: Nelson Tasman Civil Defence says the rain hasn't stopped falling, which means there could be more slips, flooding and evacuations.

It said it's unable to say at this stage when those evacuated can return home.

"This is not something we can answer right now - the properties need to be assessed for safety and we simply don't know how badly affected they are.

"In these events there is potential for serious consequences and it may not be possible for people to return home right away."

It said it's working to set-up a "one-stop drop-in shop" for support for those affected.

"We will update you on that as soon as we can."

8.25am: The NZTA says the most "significant network issues" are centred on Nelson, Marlborough and Takaka.

West Coast routes remain open.

State Highway 60 Takaka is closed between the Haldane Rd and Pupu Valley Rd intersection. There's no detour available.

State Highway 6 Nelson, Rocks Rd, is closed due to the risk of a significant slip. It's likely to be closed until 12pm on Friday and possibly longer. The detour route is via Haven Rd, Halifax St, Rutherford St and Waimea Rd.

State Highway 6 Marlborough is closed from Hira to Havelock due to flooding. A detour is available via SH63, St Arnaud.

7.50am: Speaking to Breakfast earlier this morning, Nelson resident Amy Chippendale said she couldn't return to her Nile St home after work yesterday due to flooding.

Chippendale described the situation as a "bit of a shock".

She said her mother had "frantically" packed her a bag during the day as the floodwaters rose.

"I've been lodging at my parents house for the night."

She said she'll find out today how badly her home has been affected.

"I don't know what I'm going home to."

7.40am: MetService says some places in the Tasman District recorded well over 300mm yesterday

7.30am: Speaking to Breakfast this morning, Westport resident Troy Scanlan says the town "may have dogged a bit of a bullet".

He says it looks like the rain hasn't been as bad as forecast.

He's protected his home with sandbags, as have some other Westport residents.

He says some residents are frustrated with the current extreme weather following flooding in the town in July last year.

7.20am: Here's a recap on the situation - Residents of 233 homes were asked to evacuated in Nelson following two days of heavy rain and after the Maitai River started to exceed its limits.

Ten more homes were evacuated last night in the suburb of Tahunanui, Nelson Tasman Civil Defence says.

It says homes on Stansell Ave were evacuated due to slips.

River levels lowered overnight, but plenty more rain is expected today, a Nelson Tasman Civil Defence spokesperson says.

A state of emergency was declared for Nelson Tasman and the West Coast yesterday and remains in place today.

MetService says significant heavy rainfall will continue in Nelson into today with a further 250mm to 400mm rain forecast to accumulate on top of what has already fallen.
