The lease had some tougher new conditions, including that a trust board architect must be used to supervise building work and subdivision required board consent, and the new lease was not modern but the board's attempt to further strengthen its position ready for the next round of rent reviews in about 10 years, Tillbrook wrote.
In the last round of rent reviews, the board bought back 9 per cent of its leasehold properties without compensation, he said. Several properties had forced or mortgagee sales.
"No member of the executive intends to sign it," Tillbrook wrote.
However, the board says its new lease has financial benefits, offering an initially lower payment rate for seven years, gives lessees more power to sublet or rent, enables them to develop and subdivide their land, is written in plain English and no longer demands five-year house repainting.
John Clark, trust board chairman, said the lessees have until May 7 to let the board know if they will adopt the new lease and he hopes they will.
