Last November seven people - including six overseas tourists died - after an Alpine Adventures flight crashed on Fox Glacier.

Kiwi pilot Mitch Gameren, 28, and tourists Andrew Virco and his partner, Katharine Walker and Nigel Edwin Charlton and his wife, Cynthia - all from England - and Sovannmony Leang and Josephine Gibson - from Australia - died when the chopper plunged into a deep crevasse.

The cause of the tragedy is still being investigated.
