New Zealand police say all seven people aboard a helicopter that crashed on a scenic glacier are believed to have been killed.

Police say the wreck of a helicopter has been located Saturday and was inside a crevasse on Fox Glacier.

They said in a statement that rescuers had been unable to reach the helicopter itself due to the difficult terrain but authorities believe there are no survivors.

Authorities say the helicopter crashed at about 11 a.m. on the glacier, a popular tourist destination on New Zealand's South Island.
