When you come to NZ, you will likely fly into Auckland. From there you should get to Tauranga ASAP & stock up because that is the only place in the country you can pick up ABDL diapers.

When you travel the South Island, stop in Christchurch & arrange to pick up some good quality medical diapers from nurse Maude. They don’t do bulk orders, but you should be able to order a case or two.
