I think it's better than NZ as stated. Under Part 61, everything can be done in a simulator/synthetic trainer and there are no IF requirements at all.
If you do an NDB and an ILS plus 1 other in 90 days (to get to 3 total) you are covered.
If you want single pilot you need a 1 hour IFR flight (not necessarily IF time) in the last 6 months.
How much simpler can it be?
