It would mean no residual losses fall to Whangarei ratepayers from commitments made before the Hundertwasser Art Centre with Maori Art Gallery is wound up, such as insurance, staff wages and service contracts.
Under the provision, if within the first 10 years, the accumulated losses reach $750,000 the council may cancel the lease, if the accumulated losses reaches the $1.2 m mark, council will cancel the lease.
Essentially, the council would be able to put the Trust on notice, and would be able to initiate the 'wind-up' process at a lower level of losses.
Prosper Northland Trust chairman Barry Trass said he could understand the council wanting to be cautious and cover any risks they perceived.
"But I don't think it's ever going to get to that point."
