Yesterday he made a speech that was billed to do just that. It is on Labour's website. I don't recommend it. It reads like a speech-writer's hack job.
It contained one good decision, the dropping of last year's election promise to resume contributions to the Cullen fund without a Budget surplus. That has gone into the silly bin with the removal of GST from fresh food. But otherwise it was standard criticism and empty resolutions. It was not the candid, thoughtful, personal speech I'm waiting to hear.
This is a man who has forsaken a career to go into politics for a reason and we don't know what it is. After just three years in Parliament his party made him its leader and we don't know why. Effectively he has been designated our next Prime Minister. What does he want to do?
Possibly he has not been in politics long enough to know the power of his position now. Leaders define parties. He can take Labour where he feels it should be and tell his caucus to follow him or find someone new. That is what Prime Ministers do. Key essentially gave that message to the country at the last election, defying it to dump him over asset sales. The country made its decision and that argument is over.
It will gain Shearer nothing to be out front in the hikoi against asset sales and this week he let us know he knew it, fronting in sweatshirt and jeans with the shirt hanging out. It must have been his day off.
Successful prime ministers have only one thing in common: self-belief. And sometimes they didn't appear to have it until they became Prime Minister. Helen Clark was an awkward, diffident, defensive personality, in public at least, until election night 1999.
The votes that night were like balm to her. She relaxed, bloomed and instantly became a Prime Minister born to the role.
Shearer has a lot more going for him than she did when she took over the Labour leadership in similar circumstances. He is already relaxed and likeable in public. But he lacks the confidence of his party that she always enjoyed. Even when she was failing to lift the polls she easily withstood a challenge.
Shearer would not be so lucky. Already he is in some trouble. At Parliament members on the other side are always quick to sense blood across the floor, and they sniff it now.
Shearer's main asset may be that he doesn't mind very much. He didn't seem hungry to lead the party before he was encouraged to stand and if his colleagues change their mind, he would probably nod in his reasonable way and see their point.
But I hope it doesn't come to that because politics should be better. We shouldn't expect Opposition leaders to be prize fighters for the sake of political sport. They ought to be the face of the next government long before the polls turn against the present one.
Shearer should be given room to think and speak on problems that this Government is bound to leave for Labour. One of them is the need to reconcile childcare and women's careers. Babies should not be put into care as quickly as they are. Shearer has time to put his party to work on imaginative solutions.
Another one is tax avoidance. Barely half of those in the top tax bracket actually pay their due. Shearer represents those who do. He has endorsed capital gains tax but should get after trusts too. He doesn't need charisma if he seizes his chance to do something worthwhile.
