How much is real estate commission in New Zealand?
It is negotiable and structured differently between agencies, commonly a percentage that steps down above a threshold, plus GST. Ask for it in dollars on your likely sale price rather than as a percentage.

What is a sole agency?
An agreement that only one agency may sell it for a set period. Check the length and how it ends, because it is the part of the agreement people most often regret not reading.
