Premier can reveal hundreds of people flocked to the Assumption Church immediately after the quake to pray.
The death toll from the disaster now stands at 4310 and hundreds of thousands of people are thought to be homeless.
Lilian Chan from the Christian charity Caritas is in Nepal, and told Premier the church had been providing tents, food and clean water.
"They said that they decided to go there because they felt much safer there than at their own homes," she told Premier's Antony Bushfield.
She said many had known their family members would also gather at the church so it was being used as a meeting point.
Communication problems in the worst-affected areas mean the true death toll from the disaster is still unknown.
Ms Chan was in the country when the quake hit and said it was terrifying: "We looked up and saw a two story house in front of us shake and tremble.
"One of the local staff told us to run to the open field, as the tremors continued we saw a couple of clouds of dust come up which were the buildings collapsing."
She added that it was "extremely important" to know that people were praying for rescue workers and the people of Nepal.
