Nicola Willis is defending her economic track record in the face of a lobby-group's satirical campaign.

Willis says the Government has reduced taxes and delivered significant cost savings - while keeping frontline services.
Newstalk ZB senior political correspondent Barry Soper explained why Nicola Willis is keen on making the debate with Ruth Richardson happen.
