Open an off-shore account: most commonly discussed on NZ share forums is Interactive Brokers, I do not use them. I use SwissQuote (formerly Internaxx). Can be a pain setting them up but it will be a good resource. I also use SQ for optimising my FX when needed and then transfer the cash to TransferWise (cost for that is EUR10) and to the final destination if not NZD, or direct from SQ to NZ depending on how you want to manage/optimise your FX.
