Heavy rain has flooded parts of the Bay of Plenty - including Rotorua, where a resident says it’s “scaring” her and the worst she has seen.

There are reports of streets in Tauranga also being flooded.

In Rotorua, Holdens Bay resident Joycelia Hyde told the Rotorua Daily Post that the end of Robinson Ave was flooded, and she warned people on Facebook to stay away.

“One hour ago, I could see my lawn, and now I can’t, it’s flooded.

“That’s scaring me. It’s over half of my plants, my whole back section’s flooded, it’s coming up to my back door step.“

Hyde said she had taken photos of past flooding “but this is the worst”.

“I’ve never seen it like this, and we’ve only just got the heavy rain warning, and in one hour, it flooded the section. I’m honestly feeling quite anxious about it.”

She described it as: “The worst I’ve seen it (in) the six years I’ve lived here”.

The rain was expected to ease on Friday evening.

Streams and rivers may rise rapidly, and surface flooding, slips and difficult driving conditions were possible, the weather agency said.

At the intersection of Welcome Bay Rd and James Cook Dr, there was heavy flooding, with water bursting out of the manholes and flowing to the harbour.

A SunLive reader said 11th Ave opposite Memorial Park was flooded heading towards Fraser St, creating dangerous driving conditions.

“There is also flooding as you drive through Burrows St onto 15th Ave, outside the businesses. There is flooding in both lanes. It’s very heavy out here,” the reader said.

Tauranga City Council drainage services manager Radleigh Cairns said a few areas of localised flooding had been reported across the city, with contractors responding.

“We encourage residents to take care around any flooding they encounter and to contact council if they have concerns, so we can respond promptly.”
