Which frequent flyer program should I be focusing for the future?

Due to a change in my frequent flying I have a Velocity membership about to drop back into gold. I’m wondering your views on which membership I should focus channeling my trips. I have AirNZ gold from the touch of gold promo which will drop back to silver in March and have just joined KrisFlyer from scratch. I’ve chosen these airlines because they best match my my flying pattern. Thanks

You can transfer Velocity to KrisFlyer so it is good flexibility.
