Mr Mains said while he had an employment interest in the debate on who carried out the safety audits, it was the safety of those using the rides which was paramount.
"Parents have an expectation that when they put their kids on a ride, whether it be at the Hawke's Bay Show or Splash Planet, that someone has looked over it and it's okay."
Meanz secretary John Romanes, from Havelock North, said there were two reasons why the group wanted its own certified technicians to conduct audits.
"The minor reason is that the cost of engaging an engineer was prohibitive for some clubs and the major reason is that a chartered engineer does not know about miniature railway operation," he said.
"But the criteria we now have demands that an auditor must have many years of experience not just in building but also the management of the railway."
Mr Romanes said an audit had to be completed by someone from out of the club that wanted the check done and the Havelock North club had an audit completed in Easter when it held an open day.
He said Keirunga had passed its audit.
"We have been lobbying for these changes for almost a decade. We took advice from around the world, some by email and some in person by going to Australia, the US and Canada.
"The senior Department of Labour negotiator felt it was a good system and for that reason it was put into law."
