Hi nutrition,
Thanks for posting your concern in the forum.
I understand how important recording the payment in the correct currency is. In my understanding, you are using AccountRight Premier for NZ. If this is the case, you are trying to record a payment in AUD currency. I would suggest reading through this helpful article, Working with Multiple Currencies. This has complete details on how to create work on multicurrency transactions on your file. You can expand this content dropdown to see the instructions.
If this does not answer your question, feel free to clarify the question.
Let us know if you require any further assistance with this. We're happy to help.
Thanks,
