The man was a long-term resident at the park, raising concerns there may have been earlier, similar incidents.
"We'd certainly like to hear from anyone who may have stayed at the park in recent months and witnessed any behaviour of concern which to date hasn't been brought to the attention of police or camp management," Mr Smith said.
The holiday park was a family friendly spot regularly frequented by holidaymakers travelling through the area who were often staying for short periods before moving on, Mr Smith said.
"For the majority of holidaymakers, parks and camping grounds such as this are venues for positive summer experiences. We would like to do our part in ensuring this remains the case by conducting a thorough investigation in relation to this man's activities."
Anyone who believed they may have been a potential victim was asked to contact Matamata police station on (07) 214 4263.
A 42-year-old man was charged with making an intimate visual recording and will appear in Hamilton District Court tomorrow.
