From 1 October 2016 if you’re a non-resident business supplying remote services (including online services) you may be required to register for New Zealand GST, and charge GST on services provided to customers resident in New Zealand.
You need to register for GST when:
you exceed the GST threshold, that is your sales exceed NZD $60,000 in the last 12 months, or
are expected to be more than NZD $60,000 in the next 12 months.
your customer is resident in New Zealand, and
you supply a qualifying remote service.
