This follows several incidents in the town on Tuesday night after the winter festival mardi gras.
Police returned two intoxicated 15-year-olds to their parents - a Queenstown girl who was detained at 8.30pm for breaching the liquor ban and a Queenstown boy detained at 10pm for disorderly behaviour.
Senior Sergeant John Fookes said the boy was collected at the police station by his intoxicated father the same evening.
"A lot of parents need to take a look at their responsibilities, particularly parents of young teenagers, if their kids are drinking alcohol, or [are] out late at night, or both.
"There were a large number of youths around town [on Tuesday night] and a significant number were intoxicated."
Snr Sgt Fookes said police were called to several fights although there were few arrests.
"There were some instances of youths who had caused disturbances and some incidences of disorderly behaviour.
"I wouldn't blow it out of proportion but if you have groups of any age wandering around town it's a concern.
"It's not any different from anywhere else. You will get drunken youths at some significant public events."
Police officers had a busy Mardi Gras night, he said, with two overlapping shifts of four and five officers and the full team of nine on the streets between 10pm and midnight.
An intoxicated 33-year-old Irishman was also arrested for disorderly behaviour on Ballarat St at 1am and will appear in court later this month.
Queenstown Lakes District Council Curbing Alcohol-Related Violence officer Merv Aoake and the four Queenstown community guides have been walking around the CBD between 11pm and 4am on Thursdays to Saturdays since June 27.
Mr Aoake said the guides were talking to a lot of 12 to 24-year-olds on the streets and were looking to defuse any negative developments.
They were helping drunk people of all ages to taxi stands and had administered basic first aid.
However, Mr Aoake said he was considering shifting the guides' operating hours to the earlier time of 10pm until 3am.
They would be "actively looking" for underage juveniles carrying or drinking alcohol from now on, he said.
"There are quite a few young people around at that time of night, which is a concern in different ways."
Mr Aoake said the team had not witnessed any drunken fights on mardi gras night, although revellers had told them there had been some incidents.
The guides had gone to investigate but found no evidence or people needing assistance.
"The community guides are an extra resource for the police; we don't have powers of arrest and we don't want those powers.
We want people to talk to us and our intervention is such that we would engage them and try to disperse them in a positive way and appeal to common sense."
