Mr Lints said JPs have found that more people preferred to visit them at clinics rather than their homes.
"We felt there's a need to have a lower town presence because of the changing work patterns of people. Quite a lot of people come to the Saturday market," he said.
JPs see on average 15 people a day in Whangarei.
The association has 130 members in Whangarei and Kaipara.
Apart from exercising ministerial duties, JPs also sit in District Courts and deal with minor offences, traffic matters, issues of remands and bail, hearing of undefended cases, preside over defended trials and over preliminary hearings of serious offences.
Nominations for appointment as a Justice of Peace are accepted only from MPs.
