OAC (Outreach and Church Ministries) is the New Zealand division of Open Air Campaigners. There are branches in about 30 countries. OAC exists to preach the gospel where people are, and to equip God's people for effective evangelism. We specialise in using a variety of means to arouse curiosity and hold audience attention while the life-changing soul-saving message of the gospel is communicated. www.oac.org.nz
