Can I come back to the point, however—the very good point—raised by the member in relation to retrospectivity. And the member well knows that there are legislative guidelines in relation to this matter, but let me, for clarity's sake, on the record, have it stated that the legislative guidelines that I'm quoting from, in the proactively released Cabinet paper on this issue, state that, "Legislation should have prospective, not retrospective, effect. However, if retrospectivity is intended, this must be stated in the legislation and be capable of justification."—then it has a reference. And then I refer to my previous Cabinet paper: "The repeal of the poll provisions is justified because the changes avoid community division as well as supports greater opportunities for Māori to engage in local government. The bill is also clear that all councils have until 21 May"—which I've referred to in questions in relation to this matter—"to reconsider whether to establish Māori wards for the 2022 elections, knowing that the poll provisions will no longer apply after this stage." And, in effect, that is the reference that I would draw the member's attention to in relation to the issue of retrospectivity.
