2:15pm - The Buller District Council said it is preparing for more wild weather coming its way by standing up the emergency operations centre (EOC) alongside local and national agencies.

A localised area in Granity was affected by strong sea surges on Monday morning, causing State Highway 67 to close temporarily due to debris on the road and moderate flooding to some coastal houses. One person decided to evacuate.

"The EOC is staffed and more staff are coming from outside the district," Mayor of Buller Jamie Cleine said.

Current forecasting and modelling shows it could be a similar night to last night with rain, wind and high sea swells. 

"We have mobilised resources, activated our local partner agencies, and preparations to support residents in northern Buller are in full swing," Cleine said.

Residents in northern Buller who's properties have been impacted by Monday morning's sea surges are strongly encouraged to self-evacuate to friends or families on higher ground.

"We are working with our community coordinators on assessing the situation, and preparing our communities for further weather coming in tonight," Cleine said.

People are advised to take bedding, water, food, medication, warm clothes, and to remember their pets when self-evacuating to friends and families.

"We know this is a very stressful time for Buller residents who have been through several severe flooding events in the last 12 months."

1:45pm - The Harbour Bridge is now fully open, with speed restrictions in place, Auckland Transport said.

1:40pm - June this year has recorded the second-highest monthly amount of lightning strikes since observations began in 2000, MetService said.

There's been a massive 114,765 lightning strikes recorded over and near Aotearoa in the last week (from midnight June 6 to 12pm June 13). 

"This is an immense number - and we're not even halfway through the month and June this year has recorded the second-highest monthly amount of lightning strikes since observations began in 2000," MetService meteorologist Tui McInnes said.

"There are three main factors: an atmosphere prone to having low pressure, southwesterly polar outbreaks and warmer-than-normal waters for most of the country."

The reason behind the stormy weather is the atmosphere and southwesterly polar-outbreaks.

"When we talk about polar-outbreaks, we refer to a weather system where cold air moves north, over warmer water. This is important as it creates instability, which is required for thunderstorms to develop," McInnes said.

There's also been a marine heatwave, which has intensified how active this weather has been, making the skies very electric.

"As mentioned with the polar outbreaks, colder air moving over warmer ocean is important. Throw in water that's warmer than usual into the mix, and you've added a whole lot more energy into the system; it's like doubling the baking powder in your muffins," McInnes said.

There are a number of severe watches and warnings in place by MetService, however, there is a settling trend. Wet and cloudy weather lingers around in western areas, but elsewhere expect to see the sun a bit more during the working week.

Horizons Regional Council are keeping a watching brief on rivers across the region with thunderstorms expected to continue throughout the day.

Horizons emergency management controller Craig Grant says Metservice is forecasting rainfall today to be similar to what the region has experienced over the last 24 hours.

"While we are not currently anticipating any major issues for our river systems, thunderstorm rainfall can be unpredictable so we are actively monitoring in case the situation changes and we need to respond.

"In particular we're keeping an eye on the Whanganui, Manawatū, Turakina and Mangaone catchments. Our river management staff are also out inspecting flood protection infrastructure."

Mr Grant says Horizons is in regular contact with the region's city and district councils to keep them informed of possible pressure points.

"The Makino floodgates are currently closed to divert flood flows away from Feilding and we're aware of surface flooding in other parts of the region.

"With catchments now being saturated, and a strong wind watch in place for the entire region, there is likely to be trees impacted throughout the day as well. We encourage people to take care if out and about and stay home if possible."

Up-to-date information on river heights and rainfall is available via Horizons 24 hour toll-free Waterline 0508 4 FLOOD or via our website www.horizons.govt.nz

Updates will also be posted to the Manawatū-Whanganui Civil Defence page: https://www.facebook.com/civildefencemanawatuwhanganui/

"There was the roar of the wind and that was the big thing and it was out of the ordinary. We didn't think much of it until my wife peered through the window and said the fence has gone and then obviously this morning, it's very much gone. 

"We'll tidy that up and get that to the tip. You can hear over the noise, it's the chainsaws, everyone's out, everyone's pitching in and we'll get it sorted."

"I can see all the power lines are dangling in the wind. The wind is probably the worst part of the weather this morning, it's very, very strong.

"The house was shaking, you have that instinct that it was a quake but it wasn't. Everything stayed on the walls and I was probably a bit blasé and my wife looked outside and said 'Paul the fence has gone' and suddenly it was all hands on deck.
