The Defence Force is losing hundreds of staff to Australian mining companies as low morale leads 40 per cent of personnel to consider a career change.
Defence Force chief Lieutenant General Rhys Jones revealed that the mining industry was recruiting in Devonport, home of Auckland's naval base.
Navy staff were being targeted because of their experience with heavy machinery, and departures to Australia were one of the reasons the Navy's attrition rate had climbed to 22.3 per cent.
Lt Gen Jones said Defence Force numbers often fluctuated, but departures had increased during tough economic times.
The force could not compete with mining salaries, which were often twice as large as those in the military.
