"It's annoying and disappointing, but it's kind of where some sections of our society are at the moment.''
It was not the first time a church in the area had been targeted.
Mr McBride's other parish, Scots Presbyterian Church, was in the late 1990s hit by vandals, who tagged walls and carved graffiti into wet cement.
There had not been worship congregations at the Ngahinapouri Community Church for some years but renovations on the building were nearly complete and it had been hoped services would be held there soon, he said.
"The community's lost something quite special.''
Mr McBride said there had been reports of suspicious activity in the area recently, including attempted break-ins.
"Whether that's because we've just hit school holidays and it's town kids with nothing better to do or whether there's something else, who knows.''
Police planned to distribute community leaflets appealing for information on suspicious activity, Detective Sergeant Daryl Smith, of the Hamilton CIB, said.
The fire would be treated as suspicious until evidence showed that was not the case, he said.
Fresh tyre marks on the grass surrounding the church aroused suspicions that the fire was deliberately lit, fire safety officers said.
There was nothing linking the fire to a recent church blaze at nearby Paterangi, or a suspicious service station fire at Whakamaru near Tokoroa yesterday, but Mr Smith urged anyone with information on any of the fires to contact police.
