Can you swim 50 metres in under two minutes?

In-flight crew for most airlines are expected to be physically fit and have strong swimming skills. Air New Zealand is no exception. "You will need to be able to swim 50 metres under two minutes and be able to tread water for one minute unaided." Having some in-water training is common as well, often including entering a body of water fully clothed and swimming to a life raft, where you would then assist passengers to safety. If swimming is not your strongest skill, find a local swimming pool and practice, or take lessons. That way, when this question is asked, you can assure your interviewer that you would be up to that task by the time you start onboarding.
