Since 1998 Bethel Canadian Reformed Church has carried out mission work at 6 mission posts in and around Port Moresby, the capital city of PNG. 

Continuing the work begun by the Free Reformed Church of Albany, Australia,  Bethel sent out Rev. Stephen 't Hart as missionary to work with the  congregation in Ekoro where he laboured for 7 years.  Rev. Henry Versteeg was sent in June of 2009 where he, together with his wife and other mission workers, continues to spread the gospel of Jesus Christ to the people of PNG .

The Bethel Canadian Reformed Church oversees a mission project in Papua, New Guinea.  This work is accomplished in co-operation with its supporting Canadian Reformed churches in Classis Central Ontario and Classis Ontario North.  Bethel is engaged in spreading the good news of Jesus Christ in Papua, New Guinea with the Free Reformed Churches of Australia and the Reformed Churches of New Zealand. Australia is working in Lae, while Bethel and New Zealand are working in the Port Moresby area .
