The "world's biggest waterslide", a steep hill and a big pond of water will feature at an Auckland charity event to raise awareness about depression.
The Live More Awesome charity has started building the 650m slide - the length of two Sky Towers - at a "secret location" about 30 minutes northwest of Auckland.
The public can ride the slide and two shorter ones at a two-day event at the end of February.
Co-founder Jimi Hunt said the waterslide was about "pushing boundaries and creating the ultimate summer event".
"We can't wait to see the reaction on people's faces as they come down the slides, it will be a truly unique experience."
Fellow co-founder Dan Drupsteen said the idea came about as a way to raise money while also having fun.
"We're a couple of Kiwi guys who like so many others have really suffered at hands of depression. 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'."
He said the slide idea took him "back to being a kid".
The second slide will be about 80m long and will have a jump at the bottom to send riders "hurtling through the air into a pool". The third slide will be 60m long.
The event will be held on February 23 and 24 and also includes food and music.
Tickets are limited to 2000 people and are available from http://www.indiegogo.com/worldsbiggestwaterslide
