Depends what sort of diving you prefer...
I'm not really into tropical diving, i find it gets much the same after a few dives, so I would always go with New Zealand first.
I would recommend a dive on the rainbow warrior,
two dives (maybve 4) at the Poor Knights,
One or two dives in Wellington,
One or two on the wreck of the Mikhail Lermontov
and two in Fiordland.
