ANDREW BAYLY (National—Port Waikato): I see the officials helping, which is good, because this is a change. What I'm concerned about is that the change inadvertently restricts the exclusivity covenant to just a lease, and the big issue we've got is that that might not be the case; it might be a letter. So I'm just trying to understand the rationale why that specific part of  new section 28A(2)(c)(i), inserted by clause 4, has changed from "exclusivity covenant", which is much wider, to just "the lease". I'll keep talking, if that's OK, while the Minister gets some advice on that.
