To my Astoria buddies, Mark, Mark, Steve, Pete and Trevor: we set ourselves some big challenges and we achieved them. Thanks for your enduring friendship through some really hard times. To Michael Cullen, one of my colleagues who's always had the deepest understanding and commitment to change which made a long-term difference to the benefit of people, the legacy of his many policies and laws will remain, including such fundamental shifts in people's financial security and wellbeing such as KiwiSaver, the more often talked about creation of the portfolio investment entity tax regime—I liked it—and the establishment of the New Zealand Superannuation Fund. To Helen Clark, one of the two amazing Prime Ministers I've had the privilege to serve with, thank you for your vision, your leadership, and your support.
