Mt Vernon is north of Te Heru o Kahukura / Sugarloaf / Bowenvale / Thomson Reserve / Taukahara on Summit Road, Port Hills. (we rest our case on the excessive naming activity on the crater summit!). There is a car park after 1.5 km with a great viewpoint, and from there, you can follow an informal track up 60 metres to the top of Mt Vernon.
A little further to the north is Upoko-o-Kuri / Witch Hill, which is a more interesting climb, with a rockier peak and a more interesting name.
