Campers were enjoying the sun, swimming in the pool and knocking back a few beers before New Year's Eve.
Some were consuming more than others - with one group using a funnel to drink beer.
Mr Sherson said there had been no complaints in the days leading up to New Year's Eve.
Mr Sherson said the night before was one the quietest the ground had ever had and regular campers who had been coming back for years were staying at the site.
New Year's Eve was normally pretty quiet with a peak in the camping ground at 8pm, he said.
"But the first bus leaves [for New Year's Eve celebrations] at 8pm so it gets quiet pretty quick."
Camper Meg Smith said banning adults and families from the campground over the period was a good option.
"It's a great idea, there is supervision and security, and we are keeping out of trouble," said the 17-year-old.
She said if campers acted out they are asked to leave.
Aucklander Alex Bailey agreed it was a good idea for the campground to provide camping sites to young revellers.
"It's good, it's better than being out on the streets somewhere, being arrested. It's somewhere to contains us."
