What fare bucket?
With BMI, you get 100% accrual with most NZ Economy class buckets. For NZ Business you get 200%.
Once you reach *G at 55k status miles (or 38k requalifying), any status miles you get beyond that will be turned into award miles. So effectively double miles. Plus the 25% bonus miles for *S and above.
So if you've got equivalent status with a oneworld FFP, get it matched to BD*G and you'd end up earning 225% if flying Economy and 425% in Business for your itinerary.
Redemption levels are some of the best in the industry. Especially with Cash and Miles option. 11 250 miles + GBP75 + tax enough for a one way J award to/from anywhere in the South West Pacific with enroute stopover. 18 750 miles + GBP127.50 + tax for a one way J award to/from SE/N Asia with enroute stopover, or 25 000 + GBP170 + tax for F, or to Hawaii.
