Turbulence at the Civil Aviation Authority

The resignation of Civil Aviation Authority chair Nigel Gould has come amid claims of a toxic workplace, where bullying and sexual harassment had been tolerated. Earlier this month the CAA was accused of misleading the public about the number of helicopter inspectors it had on its staff when a fatal crash killed seven people in 2015. Nigel Gould joins Kathryn to talk about his departure, along with the head of Aviation New Zealand John Nicholson.
