The address is 1880 Manawahe road Manawahe Why do I know I went to school there

Yes, it's there. On an elevated site above the road, behind trees. A closed (but not locked) gate and up a short driveway.

Couldn’t find the hall so parked on the side of the road outside the school. All OK with next to no traffic overnight. Great for an overnight stop but wouldn’t rate as a camping spot. Also the school is a couple of hundred meters away from the location given in the app.

Didn't find anything at the described location... also couldn't find anything in the other directions. Too bad for the long detour.
