The Fire Service received around 100 calls during a three to four hour period as torrential rain swept Tauranga early today. Shortly before 6am police warned the rain was causing significant flash flooding across Mt Maunganui.

MetService figures showed around 75mm of rain fell in the two hours to 6am in Tauranga.

Fire Service Tauranga senior station officer Phil Price said industrial buildings, shops and houses had been flooded, while cars had been partially submerged in parts of Mt Maunganui.

One industrial building at Mt Maunganui was badly hit, with water flowing through two floors, including through a computer suite. Water had been up to half a metre deep in some shops in the area, while some householders now faced the prospect of having to lift their carpet after water got into their homes.

“The main problem, after months and months of dry weather … all of a sudden you get a deluge and months of litter and accumulation from people’s roofs and guttering gets moved very quickly to downpipes which just block,” Price said.

“At a number of industrial premises that’s exactly what happened. It just overflowed into the premises.”

Every available fire truck from Tauranga city had been in use during the heavy rain, with others brought in from outlying areas including Katikati and Te Puke. Sergeant Steve Hindmarsh at Tauranga police said some of the worst flooding had been on the approaches to the Tauranga harbour bridge on the Mt Maunganui side.

All four lanes had been affected at one point and traffic had been stopped. Some streets in Papamoa and Mt Maunganui had also been closed because flood waters had been too deep. At one place firefighters had pushed floating cars out of an area of deep flooding, Hindmarsh said. “We’ve had a real deluge.”

Fire Service northern communications shift manager Steve Smith said around 100 calls due to the rain in Tauranga were received between about 2.30am and 6.30am, when the rain appeared to ease.

Most calls were for flooding in houses and shops, while a few people had been trapped in their vehicles by rising waters.

No one had been hurt.

The calls had started coming in from the suburb of Otumoetai, before sweeping across to Mt Maunganui and Papamoa.

Around 3.40am the MetService issued a severe weather warning for parts of Bay of Plenty west of Whakatane, with up to 100mm of rain expected by 3pm today.

The heaviest falls were expected near the coast, where peak intensities could reach 30mm an hour this morning, the warning said. Up to 130mm of rain was also forecast during the 20 hours to 6pm today in the ranges of Nelson and Motueka.

Tauranga roads closed due to flooding

Saturday April 20 2013 20:24 (local time)

Bay of Plenty motorists are dealing with closed roads in southern Tauranga, after heavy rain caused flooding.

Near the crematorium on Pyes Pa Road, State Highway 36 is closed through to The Lakes subdivision.

And on State Highway 2, the road is closed from Barkes Corner on Pyes Pa Road through to the Oropi roundabout.

Bursts of heavy rain forecast for Bay of Plenty, Taranaki, Nelson, Marlborough and eastern Otago are detailed in the latest MetService Severe Weather Warning.(below)

There could be as much as 120 millimetres of rain overnight and tomorrow.

The bands of heavy rain and thunderstorms are part of a low pressure system moving south-east across northern and central New Zealand during the weekend.

Bay of Plenty hit by flooding

“UPDATED: 7.45am Serious flooding throughout the Bay of Plenty overnight has emergency services urging residents to take care in the wet weather and stay inside if possible.

The torrential rain overnight has seen trapped cars and blocked roads with fire crews kept busy attending 72 call outs so far this morning.

Police say torrential rain in Mount Maunganui is causing significant flash flooding across the area.

At this stage a number of roads are water logged including the Tauranga Harbour Bridge, areas around Hewletts Road and parts of Papamoa with police reducing traffic to a single lane at the intersection of Hewletts Road and Tasman Quay to get through the flooding.

Our reporter on the scene says shopkeepers on Maunganui Rd are sweeping flooded water from their premises and many streets are waterlogged. Cordons are in place at several intersections, closing off areas of the Mount and Papamoa.

Tauranga Fire senior station officer Phil Price says he has not seen anything like it in quite a few years with 72 call outs attended, mostly in Otumoetai and Greerton before the Mount area, and the number rising quickly as people wake up this morning.

We had 13 on the go and 30 waiting on top of the 72 we had attended according to northern communications.

Fire appliances from Papamoa, Te Puke, Katikati and Omokoroa have been called in to help manage the excessive amount of call outs.

Phil says people need to make sure their drains and down pipes are cleared to prevent the water blocking up and flooding over.

Theres a lot of wet houses out there.

Sergeant Steve Hindmarsh says the Tauranga Harbour Bridge is very touch and go with traffic reduced to one lane to get through the flooding.

He says parts of Papamoa roads are also under water.

The best advice is dont go outside and dont drive as your car could stop from being submerged and it creates bow waves which go into peoples houses.

Driving conditions are extremely hazardous and Steve advises motorists to avoid the Mount Maunganui area until this eases.

Thank you for all the photos being sent in. We have been innundated and will make sure everyone is credited when we get a chance. Keep them coming.
