World's biggest waterslide being built in NZ

Construction has begun on the world's biggest waterslide on a hillside west of Auckland, as part of a festival to help combat depression.

The 650 metre long waterslide, the brainchild of Auckland men Jimi Hunt and Dan Drupsteen, will be open for public to use during a two-day festival on February 23 and 24.

Funds raised will be used by the charity Live More Awesome.

"We're a couple of Kiwi guys who like so many others have really suffered at hands of depression, said co-founder Dan Drupsteen. " It was really tough, but having come out the other side we decided the best way for us to keep depression at bay was to 'Live More Awesome'. We hope this amazing project will encourage others to do the same and we want people to know it's ok to ask for help," he said.
