Some tourists have taken to Trip Advisor to query the changes - with one saying it wasn't open despite a sign saying it was open from 8am daily.
The church was open when the Rotorua Daily Post visited this week.
There were two women sitting at the church entry, who said they weren't able to comment on any changes.
Ohinemutu resident Shaloh Mitchell, who runs tours through the village, said he hadn't formally been made aware of any changes.
However, he said he had noticed that the church had been closed at random times since early January.
Tourists had approached him questioning why it was closed at odd hours, and had asked him to open it.
Mr Mitchell said he had heard about possible charges or "donations".
"I have made enquiries but haven't had any formal reply."
Mr Mitchell said he wasn't opposed to the idea of a fee being charged to enter St Faith's, as long as it was fair to everyone.
He said one of his groups was asked to give a $2 donation per person but he was aware of another group that was asked to pay more than that.
"I think it is a good step, it is just how they implement it."
Mr Mitchell said he had given donations in the past, and he also encouraged those he took through the village to give a donation.
St Faith's celebrated its centennial earlier this month, commemoratingthe first church built in Ohinemutu in 1914.
The first Ohinemutu church to carry the name St Faith's was a raupo (reed) chapel, built around 1821 and named Te Hahi o te Whakapono (the Church of the Faith).
It was destroyed in inter-tribal warfare in 1836.
A second, more sturdy St Faith's was erected and consecrated in 1885.
