Some of the comments there are saying they've been on an NZ waitlist for a few years. Do you know if they're actually planning to launch here soon?
I've been using Wise for ages too and keep recommending it to people. But it looks like Revolut does more and had a slightly better (0.4%) better rate when I just looked at it then. Revolut would be even better with smaller amounts, because I think Wise has a minimum fee. Not sure if that applies to their credit card though.
If you're thinking of joining Wise...
I don't want to post it here but I have a referral link that waives the fee on your first transaction (and I get stuff too). Anyone is welcome to DM me for it.
