Salvation Army education and employment national director Gregory Fortuin said the van was being used as part of a programme helping people to get back into employment.
The programme has been running since 2014 in Northland and had been very successful, helping people who have worked extremely hard with Salvation Army support to change their lives.
"The van is used to help groups of eight to 12 people at a time travel to work in various places around Northland, which can require them driving long distances," Fortuin said.
"A member of the group who has been through a thorough screening process can be agreed to drive the van and transport other members to and from their work. This is something that we've done without a problem since the programme started."
It was unclear who had been driving when the incident happened.
Fortuin said he was unable to comment further until police had completed their investigation and any court case that might happen. The van was returned to the Salvation Army yesterday.He said the group currently on the programme are waiting to start a fruit picking job that is expected to begin in the next few days.
The arrested duo, charged with theft, will appear in Kaikohe District Court on Friday.
