It goes on to say, "Even where there has been comparable implementation and evaluation in overseas jurisdictions, the evaluation is limited." So I think we've got to be open with these measures in this bill that when we go through the select committee process and the bill may end up in a slightly different form, there will need to be evaluation measures built into these policy settings to understand if we're going to meet the desired outcome. It also goes on to say, "There is no empirical evidence to tell us how the measures will impact equity amongst the New Zealand population." And I think that's a key point, because when we look at part of the issue that we are looking to problem-solve and address today, it does show that there is inequity amongst the outcomes of the policy trajectory to date.
