NICOLA WILLIS (Deputy Leader—National): I'll just bring the committee back to a discussion the Minister of Finance was having earlier. He's very proud of his Implementation Unit, which is designed to ensure we actually get performance and delivery out of Government expenditure. Now, I'm old-fashioned. I personally think that every single Minister should have that accountability and responsibility—that is actually what their warrant is about—but he's got his Implementation Unit. So my question is: what specific areas of shortcomings in Government delivery and spending has the Implementation Unit identified?
