I recommend two branks. Anker, followed by RavPower. IMHO Anker make the best charging products on the market. My reasons for recommending these are in the many identical threads in the past discussing this same issue on here.
Since you haven't given any details of requirements (capacity is only but a small one - number of ports and QC2.0 / QC3.0 support are the most critical) it's hard to recommend anything specific.
A few months back I remember you said Anker brank should be available in NZ. Any update?
At CeBIT in Sydney this year Anker were there and I spoke to them. The impression I got was that they expected to have products in stores within a few months hopefully in both NZ and AU. That clearly doesn't seem to be the case.
