Whangarei District Council have previously said they would seek the ability to step in and potentially close the operation well before the underwrite is exhausted.

That has now taken some formal shape, with the council moving to add some new clauses to the Agreement to Lease which allow the council to wind up the project before the accumulated losses reach $2m.
