Young people have begun descending on Queenstown Lakeview Holiday Park for New Year celebrations in the resort.
A total of 1250 sites will be available for those aged between 18 and 25, camping ground manager Peter Coppen said.
This is the third year the park has ran the youth initiative and Mr Coppen said he was expecting a "bumper year''.
The fenced-off section of land is not an area usually utilised.
"This means we can have all the young people camping together in one area.
"It is easier to manage, but it is also really social for them.''
The number of sites has been reduced this year, in the interests of a "strong host responsibility''.
Anyone under 18 has to be accompanied by an adult and identification is required on arrival.
All vehicles are checked and a limit has been placed on alcohol - 12 cans per person.
"It isn't like we are locking them in. The whole premise is to ensure that all our guests are kept safe. That is why we have all these security measures in place.
"I know some people will overindulge [with alcohol]. I'm not trying to stop young people having a good time.
"It's the opposite. We want to make sure they enjoy the festivities without anything getting too out of hand.''
Jesse Lusty-Winter, of Oamaru, thought some of the security measures were a little "over the top''.
While recognising the importance of safety, he said limits on alcohol allowed on site were very conservative.
"We were here last year ... No-one misbehaved, we just had a laugh.
"I think they are being a bit too strict this year. We understand the rules, but I'm not sure if they are really needed.''
Ricky Campbell, of Cougar Security, said he did not want to be the "fun police'', and all policies were in place for the safety of those staying at the campsite.
"We've just turned away a car that had two 50-litre kegs in it.
"We don't want to encourage excessive drinking.
"They need to understand we have a large demographic in this area.
"They are not the only ones in this area. We have families in the cabins around here and we have other people camping nearby.''
His job was to ensure everyone had fun and was safe.
His 33-strong security team also had the use of CCTV.
