Martien holds a BCom from Auckland University (1975) and with a DipTchg became of teacher of economics. A BTh and a DipMin from BCNZ in 1986 saw him take up industrial chaplaincy for seven years during which time he also completed an MBA(Exec) from Auckland University. In 1993, Martien moved to Sydney, Australia, where he worked variously in his own business (business and marketing consultancy), Integratec, (video production and training company), Effective Negotiation Services (an international consulting company) and Opportunity International (a Christian overseas aid agency). These have qualified Martien to lead a new move to affirm Christians in business and employment as ‘called of God’ and part of God’s marketplace ministry.
