Here's an interesting development. BP have installed an EV fast charger at their new service centre at Taupiri. It's located at the top of the northbound Taupiri exit roundabout when coming from Hamilton. There's a Mcdonalds there, too.
This charger has both ChaDeMo and CCS 2 tethered connectors at 50kw as well as a 22kw Type2 AC socket. It was free to use when I was there on Sunday :-)
