A former Treasury economist believes the agency has lost its mojo. 

A new report's calling for Treasury to up its game, detailing a litany of blunders, including incorrect ACC deficit numbers, and costings for the Interislander ferry replacements. 

The Public Service Commission also finds some ministers are losing confidence in its advice.

He says if you don't get the right leaders at the top, problems tend to filter through the whole organisation.
