I think it's a Korean truck; didn't they come in during the mid 1990s. Can't think of the name tho. One guy turned one into a rally truck as I recall.
You're on the right track. Think more carefully about Hint 2!
Asia Rocsta, made in Korea, but I don't know where or when the picture was taken.
The photo was taken at Greenlane showgrounds in 1996 where Manukau 4WD Club built a drive course in the car park for the then Car Show. Club member Steve Mantle is driving the Rocsta
