The service wasn't launched in the United Kingdom until this year, and in keeping with the fashion of expanding the platform to even more areas, Google has officially launched Android Pay in New Zealand. Unfortunately, at the time of this writing, its availability in the country is extremely limited. As it currently stands, only folks who bank at the Bank of New Zealand and use the BNZ Flexi Debit Visa card are able to take advantage of Google's mobile payment solution.
More banks and card will likely get support for Android Pay in the near future, but there's currently no word as to when this further expansion will take place. For the time being though, folks who meet the above qualifications can start paying for things with their Android phone and begin to live out the life of the future.
