Volkswacht Bodensee - Rescuers dig for six missing in New Zealand landslide

Police said a 15-year-old was the youngest person unaccounted for after a chunk of Mount Maunganui ploughed into holidaymakers Thursday, smashing a shower block, camper vans and caravans.

Battered vehicles were carted away after being pulled out of the mud.

Voices could be heard calling for help from beneath the rubble just after the mudslide, which struck the tourist spot following heavy rain that lashed a large swathe of New Zealand's North Island.

But nothing has been heard since then, witnesses and emergency officials say.

A team of search and rescue personnel, contractors with mechanical excavators, and police sniffer dogs worked through the night and into the following day in search of possible survivors.

- No evacuation -

At one point in the search, an AFP reporter at the scene saw the diggers call a halt to their work. A police photographer was called in, and a hearse was later seen leaving the scene.

Emergency services declined to discuss the recovery of any bodies, saying it would be insensitive to families.

About two dozen family members watched the excavations from across the road.

"We have six people that we know aren't accounted for," Assistant Police Commissioner Tim Anderson told reporters at the scene.

Officers were trying to confirm the whereabouts of three other campers believed to have left the campsite, he said.

Asked if there were any signs of life, Anderson said: "Not as of today but we live in hope."

New Zealand authorities are facing questions over why people were not evacuated following reports of a landslip at the campsite earlier in the day.

"We've heard there was possibly a small slip where people did move away from from the site," local Tauranga mayor Mahe Drysdale said.

"Those questions will be answered."

- 'Complex and high-risk' -

Progress was slow as teams painstakingly cleared layers of debris, said Fire and Emergency assistant national commander David Guard.

"We are operating in a complex and high-risk environment," Guard said.

"We will continue the operation until the search is complete."

Emergency workers retrieved two bodies on Thursday from a separate landslide that ploughed into a home in the nearby harbourside city of Tauranga.

One of the dead was a Chinese national, officials said.

Prime Minister Christopher Luxon said he had spoken to families of the missing at the campsite.

"Everyone is clearly highly anxious, clearly hopeful," he told reporters at the camping ground.

"There's massive hope, there's massive worry, concern. But every individual that I spoke to is handling it in slightly different ways."
