MikeAqua:
It's also illegal to park backwards in a car park ...
You said that before and I still think you're wrong. Parking forwards is also less safe, because you're backing into traffic/pedestrians, and is stupid in the case of supermarkets where a covered walkway is provided for you to stand and load groceries into the back of your car.
The official NZ Road Code is strangely silent on this: https://www.nzta.govt.nz/resources/roadcode/about-driving/how-to-park-safely/
The AA legal advice site agrees with me: https://www.aa.co.nz/cars/ask-an-expert/legal-advice/show/9628/
