Banks Peninsula still cut off after floods hit Canterbury

The town of Akaroa on Canterbury’s Banks Peninsula will remain cut off overnight, with State Highway 75 closed because of slips and flooding that swamped Little River.

A local state of emergency was in place for the peninsula, where several hundred people remained without power and many more affected by telecommunications outages.

Little River Cafe and Store owner Cameron Gordon has lived in the settlement for 20 years but told RNZ he had never seen flooding so bad.

“This is the worst, significantly the worst by far”, he said.

“It’s the deepest water we’ve had and the most damage around town as well, no doubt.”

Gordon said the cafe had flooded five times, most recently last May when a foot of water washed through some businesses.

“We can’t do much yet, everything’s covered in water. We’re just sitting and waiting, feeling very frustrated and just over it. Well and truly over it. We’ve done this too many times,” he said.

“Our house also floods regularly with any heavy rain. We just seem to be in low land with pour drainage and seem to cop it. We’ll see what happens, see what the damage is and just go from there.”

A boil water notice was in place for Little River and Wainui, while about 250 households and businesses were expected to be without power overnight.

A damaged fibre line meant One New Zealand and Spark services were off-line but Two Degrees was working.

Civil defence chiefs said people should still call 111 in an emergency because it would go through the Two Degrees network.

Little River Campground owner Marcus Puentener said more than 300 millimetres of rain had fallen in the area, twice what forecasters had predicted.

“Two bridges are down, the driveway is pretty wrecked. A lot of water has come down off the road, out of the river and through the camp area,” he said.

“We’re trapped in Okuti Valley. There’s no power in Okuti Valley. There are slips on the roads blocking some residents in and at the bottom of the road there’s at least a foot, if not more, of water blocking any exit.”

Some tourists had international flights to catch but no way of making them, Puentener said.

Further down the road in Cooptown, Tim Wilson questioned whether there should have been more warning or greater urgency.

“This is right up there,” the long-time local said.

“Maybe it should have been a red weather watch instead of an orange but I don’t know if that makes any difference to the outcome. It’s going to be a big clean up.”

Christchurch mayor Phil Mauger said the the council was talking to the government about getting a Defence Force Unimog into the area.

“Cars can just not get through,” he told RNZ on Tuesday.

“It’s just a matter of just being able to get there with emergency services and get people out safely as well, so that’s the main concern.

“As well as getting power and comms on. People are feeling really isolated so we’ve got to sort that out as quick as we can.”

Heavy rain also caused widespread flooding in Christchurch, where the Heathcote River broke its banks.

People who lived near the river in suburbs like Opawa and Beckenham said they were used to the river flooding but the water was lapping ever-closer to their homes.

Stacey Hurst was not one of the lucky ones.

For the second time since she moved to Eastern Terrace two years ago she was mopping up in her garage after floodwater rushed in on Monday night.

“Once we realised it wasn’t going to slow down we moved everything upstairs to minimise the damage,” she said.

“We had an almost identical experience last year with about a foot of water coming into the shed.”

The wake from cars driving down the road made the problem worse, Hurst said.

“It just sends a big wave in here,” she said.

Hurst’s neighbours had avoided water getting into their homes but were shocked by the speed at which the river broke its banks, especially because last year’s floods followed days of heavy rain and coincided with king tides.

Georgia Sytema said the water rose quickly.

“This morning our whole yard was flooded, which doesn’t usually happen, it was up into the driveway. It’s a lot higher than usual,” she said.

Emeline Sales was also nervous as the water rose on Tuesday morning.

“We woke up to a big moat,” she said.

“This is the worst it’s been. It came all the way up to my husband’s car, it was quite deep this time around. It was cutting it close this time.

“It was the drains that started flooding first before the river actually broke. We haven’t had issues with the drains before but that’s what caused all the quite intense surface flooding and then the banks broke.”

Sam Guerin moved to nearby Hunter Terrace about three months ago.

He knew his home was in a flood management area and it was part of the reason he and his partner planned to knock down the house and rebuild further up the site.

Guerin said the scale of flooding was worse than anything he had prepared for.

“We were told that in one of the worst floods in the last 10 to 15 years, the water lapped at the driveway but it’s quite a lot worse than that and it happened so quickly,” he said.

“We were told the last time it flooded was before the council had done a lot of resilience measures, so it was surprising for the water to get as high as it did.”

The family had returned from a night out to find the river had burst its banks, the road was flooded and water was rising about 100 millimetres every hour.

“It was a bit of a sleepless night because we were coming out to check it wasn’t getting too close to the floor level and throughout the evening it was up on our verandah deck,” Guerin said.

“It was getting quite high, so that was a little concerning. It was under the house.”

Woolston was also affected, with Clarendon Terrace residents nervously watching the water as it washed over the riverbanks, onto the road and towards their properties.

Emily Jensen said she moved her cars on Monday night because the road had already flooded.

“I haven’t seen it that high up. I’m really surprised by how much flooding there is just after a day’s rain,” she said.

“It feels a little scary because if you were to think multiple days of rain and king tides on top of that, I don’t know what we’d be looking at.

“I would love to know the council are thinking about what to do in these areas because with climate change and everything’s that happening, it doesn’t feel so good to be down here. Five or six years ago we had a really big flooding event but the water didn’t come up the driveway at all, but now it’s coming up so it’s getting worse.

“It just creates anxiety about what you’re going to wake up to.”
