Six people have lost their jobs after adventure tourism outfit Mokai Gravity Canyon officially closed its doors.

The business, based 20km south-east of Taihape, is owned by Taupo Tourism Holdings Limited, which also runs Taupo Bungy.

It opened in 2000 and featured a bungy, bridge swing and flying fox.

As of July 4, the building and cafe had been cleared and the car park was padlocked shut.

Shareholder and director of Mokai Gravity Canyon Alistair MacDonald said visitor numbers had not been decreasing but his company did not have the money and resources to upgrade the site.

MacDonald said the decision to sell the business had been in the pipeline for a few months after they looked into the cost of a site upgrade.

"We don't have the money to expand and the idea is to sell to someone who has the money to do everything."

The company's closure left six people unemployed.

MacDonald said while the staff were only given a few days notice, he hoped they would be reinstated if the company was sold.

MacDonald said details were confidential, but there were "several substantial business parties" interested in the site.

"It's going through a restructuring process at present with possible re-ownership. It's highly likely it will be under new ownership and operating again in a few months."

MacDonald said the biggest limitation for the business was the lack of available accommodation near the park.

"A holiday park could be included," he said.

"We've got to go through a notified resource consent process yet, but it involves the DOC scenic reserve straight across the road from the complex."

"There's potential there to add more exciting additions or attractions to Mokai Gravity Canyon. The holiday park, in particular, has been my vision."

Rangitikei mayor Andy Watson said it was an "iconic attraction" and hoped to see it back up and running soon.

"It's an iconic attraction and a stunning piece of scenery. I'd love for it to continue.

"It's not only an amazing attraction, it's also an employer of our district."
