Hmm, you've confused me though that isn't too hard these days.
"to New Zealand using your reward points", I presume you mean Bonvoy points?
"We are also destination club members, but we have never deposited our week for club points.". So, here, you are speaking of depositing your week for destination club points? Or, depositing it for more Bonvoy points?
There are no MVCI resorts in New Zealand, though there is one near Brisbane Australia which we visited 3 times now. There are a fair number of resorts you could trade into in New Zealand. Just not clear if you are thinking hotels or resorts. And how your destination club membership plays into it.
When we made our last Pacific trip, we made a stop in Fiji on the way to Australia, there is a nice Marriott "hotel" there. We had an over the water bure, points paid. Made the flight a little bit shorter.
