Hi Dogberry and
to MoveToNZ.
NZ is pretty desperate to stock up on police recruits as they are very short staffed. The police force can't seem to hold onto people for long which is part of the problem. There have been some articles in the press about it from time to time. It's possible that part of the problem is that NZ police sometimes find it hard to take on board new ideas from their migrant counterparts who may be used to doing things a different way.
