New Zealand citizens are taxed on ALL their overseas earnings if they have an enduring relationship with NZ. The definition of this 'enduring relationship' is far reaching and a look at the IRD website will show what a minefield it is.
Any Kiwis working in this part of the world should have a good look at how their personal circumstances stack up with the IRD's interpretation of things or they could have a surprise in the future.
