Hi MrsD and welcome.
If you are talking about a NZ income of between $200-$250k per annum, then I would say you would do very well, especially if you are going to use your capital to buy a house, rather than rent or take on a mortgage. Even with housing costs that would still be a darned good income. I think many NZers would dream of having such available funds. Of course, how you spend them would depend on how far your money would go. Living the high life would drain your bank account quickly but, if you tend to live modestly and save up for holidays and treats, you should thrive.
