FYI: you can also book an AA award on FJ for AKL-NAN, no need for a payed fare as long as you book in advance.

And I don't agree that Fiji is not nice. Whem limiting hotel options to SPG, it will likely seem to be the case. I am at the Westin Fiji right now and I can only tell to avoid it (same for the neighbouring Sheraton). Luckily I am only here in transit before heading to Taveuni later today. Fiji is very nice as long as you are willing to pay the same rates for luxury resorts as in Tahiti. Which means you will have to stay away from SPG in Fiji. Unless you want a spa suite with a plunge pool for your honeymoon with 0 privacy, I am overlooking at least 3 plunge pools as we speak from my higher floor balcony .
