"We believe that someone who is abusive towards their family is not fit and proper," Naylor said.
Raising the query helped make sure police were keeping on top of training vetting agents and evaluating their processes, Naylor said.
Police director of partnerships, arms safety and control Superintendent Mike McIlraith told attendees at the meeting applicants should never be interviewed in the presence of their spouses and called for examples to be provided to police.
The FCAF was set up last year as part of the Government's efforts to reform New Zealand's firearms licensing regime in the wake of the March 15 terror attacks.
McIlraith told the ODT no examples were provided and the issue was not raised again at a subsequent FCAF meeting.
"Significant refresher training has been undertaken in the past twelve months for our vetting staff to ensure they are equipped and enabled to do the job required of them," he said.
Training around interviews had included the need to ensure interviews are conducted with no one else present, McIlraith said.
He said the new firearms regulator would also work to ensure interviewing policy was consistently practised nationwide.
