Mark & Katrina Trewavas

Asia North-East Thailand

Personal Profile

Mark and Katrina signed up for a church missions trip that changed their lives, giving them a passion for missions. In 2000 they became the pastors at the Hawera Assembly of God church and served there for 12 years. During that time they attended a missions conference where they heard that even though the Western World has had access to the gospel for about 2000 years, there were still places in the world that had yet to hear the Good News. In 2012 they resigned as pastors and with their four children, Levi, Sophia, Samuel and Izaak they settled in in North East Thailand.

They led their church in adopting a least reached people group, called the Isan. At the same time God was working in their hearts about going to this area themselves as missionaries. In 2012 they resigned as pastors and with their four children Levi, Sophia, Samuel and Izaak they settled in North East Thailand serving with Mekong Evangelical Mission.


The Trewavas family now live in North-East Thailand among the Isan people. The Isan people have traditionally been neglected, inhabiting one of the poorest and hottest parts of Thailand. The people strongly adhere to the Buddhist religion. There are 18 million Isan people but only 1 person in every 500 are Christian, (compared to NZ”s statistics of 1 in every 10 people). In 2014 they shifted to a village to help plant a church in rural Thailand believing that the light of Gods love will shine in the hearts of the people in this area.

Their current ministry includes:

  •  training local Christians and churches in evangelism
  • teaching English and sharing the gospel in school
