I did my license conversion CASA to CAA and AS350 rating with the crew at Helicopters Nelson and what a awesome experience it was, cannot recommend a better place to do it. Very close to the mountains makes it a great spot to get that experience up with hut landings and confine spaces of all levels from basic to tricky, snow landings at the right time of the year and long line situations that require short and longer lines to get that real world situation awareness/experience.
