Otorohanga's night security guard says McDonald's has become the "breeding place for trouble" with teenagers using the excuse of getting a burger as reason to gather there in the early hours of the morning.
Pearl Security guard Denis Kaumoana said people gathered at McDonald's after the pubs closed in the early hours of the morning and fights broke out.
Mr Kaumoana said the problem had escalated since the 24-hour McDonald's opened in 2009 because it gave teenagers an excuse for hanging around the town at all hours. McDonald's said its restaurants did not make any difference to the levels of trouble.
"Since McDonald's has come to town it is always a breeding place for trouble - fights, disorder, assaults and just congregation of trouble-makers after the water holes close down," Mr Kaumoana said.
"A lot of the ones up to no good, if you pull them up in the street and say to them what are you doing out this hour of the night - they always say we are going to McDonald's.
