Hey,
We have just come back from a trip which we booked using Airpoints Dollars I have purchased using my OneSmart card. EG: topped up my OneSmart each payday and then converted these funds to Airpoints Dollars. We found this a great way of saving for our trip as we couldn't then spend the money on other things.
However I just looked into restarting the same process for our next trip only to find out that you now can't do this. I tweeted AirNZ and was told the only way to now do this is to have a Kiwibank Credit Card, something I don't have or want.
Poor form AirNZ, very much a backwards step in my eyes. Guess we'll just have to be a bit more disciplined with our savings.
