Chris Hipkins is hitting out at the Taxpayers' Union as it prepares to launch a campaign against Finance Minister Nicola Willis. 

The lobby group is questioning Willis's track record on the economy. 

Willis has responded, challenging chair and former finance minister Ruth Richardson to a debate. 

The Labour Leader told John MacDonald the Taxpayers' Union has a view of "entrenched privilege". 

He claims the organisation is funded by a group of rich people who want to keep all of their money. 

Hipkins is also unimpressed by Willis’ decision to agree to the debate, which he says shows deep divisions among the National Party. 

He calls it petty and says Willis should be focused on things like creating jobs.
