The sustainability is really important. If we look at what's happening in New Zealand at the moment—the impacts of COVID—there'll be significant debt that's taken on by the Government, and that'll be for future generations to pay off. So it is really important, on this side of the House, that we have a New Zealand Superannuation scheme that is sustainable. We were disappointed that Jacinda Ardern had the opportunity to also stick with their former policy of lifting the age of entitlement but backed off it. We would have preferred that we could have had a situation across the Parliament where there was general agreement about making the New Zealand Superannuation scheme more sustainable for generations to come.
