New Zealand does not have capital gains tax on property, so therefore there is only the US tax after expenses. I was just on the NZ website to clarify this.
Please review this guide (scroll to page 5) from the NZ tax authorities. It indicates that where a person purchases property with the intent to make a profit, that the profit is taxable. Consequently, NZ does in fact have a capital gains tax, which may apply to your circumstances.
I hope that you will reconsider your previous rating and provide a positive rating of my services.
Thanks in advance.
