Catholics are being called en-masse to attend Mass in Ross to save the town's last remaining church from closure.
Christchurch Catholic Bishop Barry Jones will lead Mass in the 149-year-old St Patrick's Church next month as part of a diocesan visit to Westland.
Last year, parishioner numbers fell to just three, raising concerns for the future of the oldest church on the West Coast.
Parishioner Biddy Manera said the more people who could attend August 9 Mass, the better to show the significance of the church to the community.
Ms Manera said while Mass numbers were not high at Ross, members of the Kokatahi-Kowhitirangi congregation, as well as visitors, often joined the twice-monthly Masses.
