Thanks for all the tips everyone.
Another question without starting a new topic - is it best to convert to all currencies needed now, or just leave in NZD and choose to pay in local currency each time? We'll need a few currencies (Pound, Euro, Swiss) so for what is left in one will need to be transferred to another once finished using that currency. Does keeping it all in NZD work out better than transferring to Euro, then again to Pound once finished with Euro?
I guess it really comes down to your view on what the FX rates are going to do - which isn't easy. If you think Kiwi could get weaker then change now, and vice versa. If you have no view and don't want the risk, then estimate your needs and change now. In that case, also have some as backup in NZD.
Wise is pretty good at taking money from other currencies 'on the fly' as needed, including automatically splitting a payment between two (or more) available balances. e.g. we had paid an accom bill in Canada greater than our CAD balance, Wise automatically used all our CAD balance and then topped up from our NZD balance (converting at the spot rate at the time). From that point, my view was that NZD was appreciating vs. CAD, so we left everything in NZD and let Wise transfer on demand when we spent CAD. We only did that in a 2 currency situation, but I'd assume Wise would handle using 3 or more currencies in one payment. So probably no real need to keep changing from currency to currency.
