Winch accident in New Zealand, can low time student pilot be blamed?

I belong to the club where this happened .
The inquiry is still going on but from comments made by
people actually there when it happened.
The pilot had already flown earlier in the day in the same glider.
The witnesses said the pilot rotated early and was a bit steep in the
initial climb but then started to turn right when in full climb
at around 300 ft, the deviation to the right continued until back release
occurred when the PW5 promptly rolled into a spin.
Partial recovery seemed to happen and the PW5 landed straddling a
driveway. The farm type 7 wire fences on either side of that driveway
acted like arrestor wires.The pilot has 2 broken ankles a
broken arm and other minor injuries.The pilot I think is from Hong Kong
and I believe has already been flown home.
The PW5 is known to want to go to full climb quickly if not prevented
but I know a Nimbus 2 will do exactly the same if winched a bit quick so
don't blame the glider ,this accident has the look of pilot error.
A lot of the training here is on the 2 seat PW6 so type conversion problems
are likely not an issue.

Correct "CG" release was used, which on PW5 is offsett forward of the
CG.
I was told that the nose hook is not allowed for winch towing of PW5.
That's what manual sais, but who knows why?
Which other gliders are not allowed to be winched by the nose?
I was told that PW5 has front and rear ballast weights, how
complicated is it?
Who is resposible for checking weight and ballance, if for example
student pilot has 3 hours (40 flights X 5min) of flight experience?
When does resposibility of flight instructor end?
