It's stunning how many people seem to forget that there are other countries on the planet that use dollars and weren't involved in Vietnam. No, I'm not making an assumption. The person who posted this is Canadian.

Wellington has had a heated property market longer than most places - it's hilly for a start, so can't just sprawl like Auckland, and it's the capital, so a lot of well-heeled bureaucrats who don't want to commute from the hinterlands. I don't live there any more, so I don't know what the rental market is like now.
