In early March the organisation announced a proposal to shut all of its 21 centres, which collectively employ 88 staff and cater for hundreds of students.
The Oamaru centre, funded by the Tertiary Education Commission, offers life skills and career option advice, NCEA level 1 and 2 qualifications and New Zealand certificates in tourism and computing.
Earlier this week, Salvation Army assistant territorial secretary for programme Captain Gerry Walker confirmed to the Otago Daily Times the proposal, signed off by the organisation's territorial governance board, would go ahead as outlined to staff and students during the consultation process.
He said the Salvation Army had "worked hard" to keep the centres open, but was unable to sustain the costs involved with running them.
The decision has been made as the model for funding education and employment is unsustainable. For the past five years, the Salvation Army has been funding education and employment from reserves. At the same time, student numbers have been falling and funding has become increasingly difficult to secure.
"Under the current funding model, if the Salvation Army continues to fund education and employment as it has been, it would have to cut other services."
Current staff would be redeployed in to other services within the Salvation Army, offered retraining, or as a "last option", redundancy.
Students would complete their courses if possible, or it would be arranged for them to complete courses through other providers where possible.
Oamaru education and employment centre manager Joseph Cropley, who earlier voiced concerns about the closure and its potential impact on students, declined to comment specifically on the closure.
However, he thanked the public and stakeholders for their support and hoped students would continue on their current path.
All centres will close their doors on June 30.
