Well I have been a kiwi bank gold for a few years and they have been fine , but I switched to a ANZ platinum earlier this year for the status points and koru discount. Now to my surprise I got a letter today to say my kiwibank gold card is going to close and they have upgraded me to the new AIR NZ platinum card - at no extra cost for the first year.
So overall a good result , now to decide what card to keep.
