Pressure is mounting on Prime Minister John Key to authorise a formal inquiry into former ACC Minister Nick Smith's involvement in his friend Bronwyn Pullar's case amid speculation about the past nature of their friendship.
During a snap debate in Parliament, NZ First leader Winston Peters called for Dr Smith to resign or be removed from Cabinet, describing the furore as "a shabby little case involving blackmail, sex, a minister with a conflict of interest".
And Opposition leader David Shearer last night called for Dr Smith to resign or be sacked for trying to influence ACC's treatment of Ms Pullar.
The Greens called for Auditor General Lyn Provost to investigate the matter, and said Dr Smith should be stood down until that is completed.
Ms Pullar is the former National Party activist who was accidentally sent information about 6700 other ACC claimants, including data which identified some as making "sensitive claims" for injuries resulting from rape or other forms of sexual assault.
