The aviation watchdog is assuring a Christchurch coroner it has lifted its game in the six years since a helicopter crash killed seven people.
Queenstown pilot Mitch Gameren, 28, and six tourists were killed when the Alpine Adventures' helicopter he was flying crashed during a scenic flight over the Westland Tai Poutini National Park in November 2015.
British tourists Andrew Virco, 50, Katharine Walker, 51, Nigel Edwin Charlton, 66, and Cynthia Charlton, 70, and Australians Sovannmony Leang, 27, and Josephine Gibson, 29, were also killed.
Coroner Marcus Elliot is this week holding an inquest into the ill-fated flight with the aim of seeing if further recommendations could prevent something similar from happening again.
