Jim Tucker, who was a day boy at NPBHS and later became a well known journalist, was one of the brothers who organised the event.
Here are Jim's memories of the venue:
We lived in Mangorei Rd over the road from the girls high and on the property was our father's bakery building (it's still there). He sold out in 1962 and continued to use the place for various food distribution businesses, then finally rented it out for storage.
The loft was the old flour loft, reached via a steep set of steps, a long, narrow, wood-lined, attic-like room where the sacks of flour for the bakery were hoisted, to be emptied into a bin and fed via a hopper down through a big seive into large metal bowls on wheels, in which the bread dough was mixed by a giant mechanic device.
We took it over and pasted it with coloured pix of movie stars from a magazine called Playdate, equipped it with a couch-bed (no doubt with thoughts of seduction in mind - they remained merely thoughts, given the old man's vigilance), a sound system of sorts, and a would-be bar.
The band would turn up on Sunday afternoons for practice sessions, to which we invited friends and those members of the GHS boarding establishment with the courage and wit to smuggle themselves across the road.
It was a great place for music sessions. However, it ended in near disaster when word got out during the weekend of the 1965 surfboard champs that we were having a party there, and hundreds of gatecrashers converged. One lot tried to run the old man over in the driveway, so you can imagine what happened next. The place was closed down. A pity. But great while it lasted.

Jim adds: I was a day boy at NPBHS from 1960 to 1964 inclusive, and I'm keen to track down a boarder from that era named Geoff Robinson. He was from the Waikato, I think. Anybody able to help? Many thanks.
