This probably isn't much use to you, but I did it 25 yrs ago.
The procedures then were very similar. NZ was, at the time, closer to ICAO than Oz.
Did the IR exam and the equivalent of an initial issue ride with an ATO.
No big deal. I suspect it is simpler today than in 1986.
Someone in here will be able to give you the good oil.
