Youth crime is no worse in Whangarei than other centres in New Zealand and has remained static for the past two years, police say.
"We have peaks and troughs in certain areas but in general it has been fairly static," Whangarei Youth Aid Sergeant Rob Nordstrom says.
Youth offending - offences committed by those under the age of 17 - accounts for about 24 percent of burglaries, thefts from cars and unlawfully taken vehicles in Northland, Mr Nordstrom said. No statistics were available for violent crime.
However, back in May a police report to the Whangarei District Council showed a 15 percent increase in juvenile offending referrals to Youth Aid.
Youths under the age of 17 were responsible for 50 percent of dishonesty offending, 19 percent of violent offending and 10 percent of sexual offending in the Whangarei district.
In the report, Whangarei and Kaipara police Area Commander Paul Dimery also said there had been a noticeable increase youth offenders aged 10 to 13.
Youth lawbreaking appeared to be tracking a similar growth in the overall youth population in Northland.
Those aged between 10-24 are expected to account for 23.3 percent of the population by 2010, Mr Dimery said.
Mr Nordstrom said about 20 percent of the youth population commits about 80 percent of the crime, and only 10 percent of referrals to youth aid are repeat offenders. Acting Whangarei/Kaipara area controller Inspector Murray Hodson said the root causes of youth offending were complex. Many of the young people aligning themselves with "youth groups" - commonly known as gangs - in the city came from dysfunctional families, didn't identify with anything and often had no idea what they were getting involved in.
"It's in their formative years.
It's whether parents teach their kids right from wrong in early childhood."
However, he believed alcohol abuse was a major contributing factor in crime.
"We have a culture where alcohol is acceptable. Unfortunately when young people obtain alcohol and drink excessively that's where the problems occur. But what we do know is a lot of the problems that happen in town on a Saturday night are caused by people over 18 because they're drinking excessively," he said.
"It probably wouldn't happen if they weren't under the influence of alcohol."
Police are also concerned at the number of children being relocated from South Auckland to Northland.
"Anyone who is from South Auckland culture that is being relocated to Northland for whatever reason could bring problems with them," Mr Nordstrom said.
"What happens in South Auckland is a precursor to what happens in other areas later on."
Northland police have several initiatives targeted at youth, including a big brother service, a youth education service, campus cops in schools and the youth aid service.
Whangarei police have also beefed up their presence in the central business district. Other police initiatives included a youth development programme aimed at early intervention for at risk youth.
