"This was an isolated incident and in no way related to my role as mayor," he told the Chronicle.
Mr Cameron said the Raetihi community had rallied around him and his wife.
"People have been especially upset that my wife is involved, as she has been incredibly active in working for the community, including its youth.
"It is important we keep things in perspective and don't allow this incident to derail the progress being made in building connections with the Raetihi community."
He would like the public to know both he and his wife were shaken but okay.
"It's one of those unfortunate things - we happened to be in the wrong place at the wrong time. It happened so quickly and it was over just as quickly."
The couple were treated by ambulance staff at the scene.
Last night police said they had arrested three people in relation to the serious assault of a couple in Raetihi.

Inquiries into the incident continue.
