New Zealand's WWI tunnels in France uncovered by using laser scanning technology

The history of New Zealand's World War One underground tunnels in France has been uncovered by a group from Otago University, using laser scanning technology. 

In 1916, the New Zealand tunnelling company extended quarries below the town out to the German front line from where the allies launched a surprise attack. 

Richard Hemi from Otago University came up with the idea to capture the subterranean world using a laser that shoots points and measures where everything is, creating a 3D model video.

"As I looked into this story, I was surprised at how little people knew about Arras and these tunnels and to it was somewhat an untold story," he told 1 NEWS. 

"We do a scan that's maybe five to six minutes long and just scans everything in a 360 circle we then put the camera on which takes a panorama and puts colour of texture to the point cloud."

For nine weeks, the team worked underground alongside French students and lecturers to ensure the tunnellers legacy would be preserved.

Police working to locate man missing in water at Hunua Falls

Emergency services are working to locate a man who reported he was having trouble in the water at Hunua Falls last night.

Emergency crews were called to Hunua Falls Road in South Auckland around 11:15pm last night.

A St John spokesperson said the man made contact with St John whilst he was floating down the water, but his phone cut out around midnight.

"It wasn't a very good phone line," he said.

While emergency services continue to locate the man, a police spokesperson said it is likely the man is now out of the water.

"Police are following strong lines of enquiry at some addresses now," he said.

More to come.
