Mangaweka is now live today! Hasn't shown up in the car maps but the chargers are live. Just so happened that I was on a trip to Palmerston North this evening and was one of the first to use it
I was only to max at 67kW and a person before me only maxed at 77kW on a lower SoC. Seems they might be limited to 77kW like the Timaru superchargers, however neither car was able to precondition due to the cars not knowing of their existence yet:
