Thanks, I've been waiting for info on Teretonga but it's been delayed for various reasons (being on the other side of the planet doesn't help) so I've been getting on with the basic layout of Pukekohe instead.
How good is your memory? Could you talk us through a lap? It would be great to know about camber, dips at apexes of corners, large bumps and elevation changes. So far I've got:
A slight rise over the start finish straight (they moved the startline back to the end of the pitlane in '65 I think)
Slight downhill to the Elbow, maybe a dip at the apex? Hard to tell. - never noticed a dip
Out of the elbow past the stables and under the Dunlop bridge
Downhill entry into the GP loop... but how sharply downhill? Cars seem to disappear in the footage. - drops away a bit to the corner- about 10-15ft
Track levels off as the corner opens up and then a fairly level run up the the 90ish degree corner alongside the railway
Slight uphill entry into this corner, maybe slight dip in the apex here too? - a slight steady rise all the way up that straight to Railway...prob about 6-7ft overall
Long straight alongside the railway with a very slight crest where the tracks bends to the right - yes...have done it at 170mph on a GSXR1000, 10 yrs ago, and it seemed tighter than it looks! All slight rises, then dropped off about 3-4ft . to the hairpin, which had a good camber on it, and lots of seal joins!
Level or downhill entry to the hairpin?
Hairpin seems very cambered and bowl shaped, now there's a huge dip at the apex but was it there in the 60s? - yes
Fairly level exit from hairpin, slightly longer straight than now where the following corner has been eased
Then an uphill left hand bend that's much tighter than the current layout, followed by a dip down where the run off areas narrow over a ditch
Then uphill again and a right hander (alongside a cut in the bank alongside the track)
Then another dip and rise over the start line again - yes. the faster cars could bottom out at this dip coming down from the hill
Some first hand info about the circuit in the 60s would be invaluable!

I've already trawled though theroaringseason.com for Teretonga info, will do the same for Pukekohe..... it's a fantastic site full of great info and enthusiam. A bit like SRMZ really!
