But the most telling moment was when he was asked if he would make the well-off pay more tax. His response of "you bet" was the kind of direct answer that's been missing from Labour's lexicon for a long time.
But then there was not a lot that was subtle about Cunliffe's confirmation that he was entering the leadership race with Grant Robertson and Shane Jones.
Cunliffe's evangelistic catch-cry of "a new beginning" for Labour under his leadership would have done a southern revivalist preacher proud. The gospel Cunliffe is selling can be summed up in one word - hope. That only he of the three contenders has any hope of turning the tables on John Key in the run-up to next year's election.
The virtuoso routine came on top of a TVNZ poll which shows close to 30 per cent of voters think Cunliffe is the best person to lead Labour after David Shearer's resignation. In contrast, Robertson and Jones struggled to break 10 per cent.
Cunliffe's razzmatazz also stole a march on Robertson, who announced he was entering the race via press statement and Jones, who simply confirmed his intention to stand to a Herald reporter.
It is all designed to give Cunliffe's campaign unstoppable momentum - or at least the impression of it.
The complicated voting system adopted by Labour means Cunliffe must capture the bulk of the votes of the ordinary membership to offset the strong support that Robertson has in the caucus.
To win the ballot, Cunliffe needs to project himself as winning and hope snowballing support will shift enough MPs fearful of ending up on the losing side into his camp. But yesterday was all about reaching out to the wider party outside Parliament. And, on that score, he is so far making all the running.
