The Dark Sky Project in Tekapo which opened in July 2019.

Tekapo's $11 million Dark Sky Project has been mothballed for the next few months.

A decision will be made later whether the fully immersive dark sky experience, which opened in July 2019, will be able to reopen, a Dark Sky spokesperson says.

"With no international (visitor) entry to New Zealand and the on-going NZ alert Levels it is likely that the Ngāi Tahu tourism operations will remain closed for the next several months.

"As a result Ngāi Tahu Tourism is undergoing a proposed restructure to reduce costs down to that required to maintain the business in this hibernated state."

Dark Sky Project, Huka Falls Jet (Taupo) and Shotover Jet (Queenstown) will be closed for the next few months at least with a decision to be made about reopening when domestic travel builds, they said.

A decision on reopening a number of other operations owned by Ngāi Tahu tourism will be dependent on the resumption of international tourism.

"This process may result in significant job losses which would be devastating and regrettable," they said.

"However we believe it is necessary to ensure the viability of the business for the future."
