Mr Davis said the drop in general duties constables in Northland could be the reason for these statistics.
"People who are being burgled want their stereos back, their televisions back and the offenders caught. Yet nine out of 10 times they get away with it," he said. "Police are doing all they can."
Mr Davis said increasing the number of general duties constables in Northland would mean the region would be safer. While on his anti-violence hikoi he stopped in at Whangarei Girls' High School yesterday where he said one girl was "distraught" talking about how her mother was assaulted walking through the main street of Whangarei.
"A safer Tai Tokerau, that's number one," he said.
Northland was not the only region that had a drop in the number of general duties constables - all 12 districts except for Counties/Manukau had a decrease.
