The response from the community in a time of need has been remarkable, Calvin Community Church pastor Ken Williams says.
The church became one of several community evacuation hubs during the state of emergency caused by flooding this week.
It opened at 4pm on Tuesday and had an influx of community members and organisations offering support.
About 25 people were volunteering at one time, for tasks ranging from washing dishes to dropping off baking and bed linen.
“I think it’s a pretty good reflection on what type of community Gore is,” Mr Williams said.
“If people are in a spot of bother people are always happy to help.
“It’s been incredibly encouraging.”
About 50 people, mainly tourists, used the facility on Tuesday night after they found themselves unable to leave Gore.
“They found themselves stuck at the end of the day and then some residents self-activated.”
Resthaven Retirement Village residents arrived at 1am on Wednesday and by 3pm about 200 people had been in the church.
The church would not turn anybody away and was working closely with the other two Gore hubs, at the Heartland Hotel Croydon Lodge and Gore High School.
The church had not been affected by the rain, he said.
The church became an activation hub with the help of Emergency Management Southland last year.
