From the horse's mouth:

Can I transfer Airpoints Dollars™ or points between frequent flyer programmes?
Answer:
No. When you earn Airpoints Dollars, points or miles in one frequent flyer programme, they cannot be transferred to a different programme. Star Alliance frequent flyer programmes are independent and separate, therefore we cannot transfer your Airpoints Dollars, points or miles between them.
However, you can earn and use Air New Zealand Airpoints Dollars when you travel on any of the Star Alliance airlines or use Airpoints Dollars to travel on our airline partners.
