"I'm proud of the work Te Ahu does for our community and I'm proud of my involvement with that organisation."
National's campaign manager, Steven Joyce, said the council review had nothing to do with Mr Osborne. "My understanding is there is no relationship with Mark Osborne."
He said the campaign team had discussed the issue when it was raised in the past. "He said there's nothing to it and we've had that checked with the Far North District Council."
However, a submission Mr Osborne sent to the council in April last year raised concerns about the review. Written by trust chairman Mike Mitcalfe, it noted: "The trust is aware that a review of the relationship between council and Te Ahu has been initiated by the FNDC chief executive, but has no knowledge of the brief or scope of that review and to date has had no involvement in the review. We seek immediate involvement through our general manager [Mr Osborne] to ensure participation and transparency of process."
The same submission also raised concerns about the council underfunding the trust. It said the trust had been left out of budget decisions affecting areas it had responsibility for. One concern he raised was under-budgeting for repairs and maintenance - he said $10,000 for a facility valued at $14 million was "grossly underprovided" and asked for $50,000.
He also objected to the lack of a budget to market and promote the centre.
Mr Osborne became assets manager at the council in October, when his trust job ended.
The council started its review of the trust last year with the aim of establishing greater accountability and separating management and governance, NBR reported.
