Finance Minister Grant Robertson is the midwife of the PM's Year of Delivery. Claire Trevett went for a pre-Budget drive with him to check on progress, assess the wellbeing of his household budget, and find out which ministers he finds it hard to say no to.

Finance Minister Grant Robertson is standing on top of a hill looking over the Wellington Central electorate and a park bench with graffiti on it: "Cler is a [very bad word]."

"Oh look," he says, "they've spelt Claire wrong."

It was a rather brave opening gambit, given our hour-long expedition had just started.
