Hi All
I've got a crazy idea but just wondering if it's possible.

Is it possible to book fantasy domestic NZ flights using Airpoints dollar (with no intention of using them) and then cancel them turning them into a credit?

The website seems to indicate this is the case which would perhaps prolong expiring airpoints? Is my understanding of this correct?

If doing this does it take a long time to cancel NZ domestic flights and receive the credit back and would it make a difference if it's a flexidate fare?
