It certainly looks like Stripe will be available in NZ soon. They have New Zealand listed as being in private beta on their website. We are certainly looking forward to it. Looking forward to built in merchant account, subscription and recurring billing features, and multi-currency.
Also would be good to get Xero Stripe integration, which is currently only available for non-NZ stripe customers.
Official answer from Stripe on timeframe is “We can’t give you a timeline just yet, but you can signup to be notified once we’re available here ()”
