"I have worked with our youth at risk in Wairarapa and it is overwhelmingly obvious that we desperately need to put the work in at the early years," Mr Esau said.
There are 35 Community Trusts around New Zealand which teach 225,000 primary and intermediate school children each year.
Mr Esau said donations are essential to continue the service.
"As chairperson, my job and the job of our Trustees (who are all volunteers) is to make sure that our mobile classroom is able to visit every one of the 68 primary schools in our region - annually, or biennially.
"We rely on grants and donations to fund this operation and appreciate every cent that we can get towards reaching this goal," Mr Esau said.
