"You can identify areas where there has been a rise in crime," said Mr Quedley.
"I offer suggestions when I see that we need to do something, whether it's the police who do it or community patrols."
Neighbourhood Support has been operating in Rotorua since 1995 and Mr Quedley said that relationship had been built on years of trust, especially on what was done with the information shared with them.
"There is some information that we are not allowed to pass on, so that trust relationship between the police and Neighbourhood Support has been going on for all those years and it continues to go on." He said they had a database that was used to send out e-alerts to a street's contact people. "Then they distribute it to the members of their group. It can be as simple as, 'There has been a group of burglaries in your area so be on the watch for anyone suspicious.'"
Mr Quedley said he kept note of each time there was an occurrence, and said data showed less crime in Neighbourhood Support areas.
"To be a member of the group, it's not a silver bullet that will cure everything but it increases the level of awareness in the area.
"It does reduce crime because people know what to look out for," Mr Quedley said.
He said the main benefit of Neighbourhood Support was making people aware of their own security, building community spirit, and getting neighbours to talk.
"We like the idea of people talking over the fence line so that they are actually face to face."
