IFR ME Types in NZ.
AW 139, AW 109 E + S
EC135 + H145 and some BK117 IFR maybe??
B222 + 212?
Not all would be available to hire of course.
Outside of an IFR Operator it may be hard to schedule any sort of skills test unless you work for the operator.
Plus you will need to do Mountain and Sling if not done already - it is part of the licence and not optional.
