Actually, the Kiwi dollar is even worse than that, in that it actually equates to £23,000.
But regardless, what's the point of converting it to British Pounds? He's living in New Zealand, working in NZ, and probably going to stay there for most of his life (before he sneaks over to Australia).
Earning NZ$60G is similar to earning about UK£42 comparatively, when the standard of living etc is taken into acocunt. Not a bad trade off when yu live in one of the best countries in the world (politicians aside).
J27, that's a great starting salary if true, and I wouldn't worry about the future wages right now. Just get stuck in and enjoy your job. You're on a good wicket.
