ACC Minister Judith Collins insists she will continue with defamation proceedings against two Labour MPs and Radio New Zealand.
Ms Collins is taking legal action against Trevor Mallard and Andrew Little for comments they made during an interview with the state-owned broadcaster over the leak of an email sent to her by former National Party president Michelle Boag.
The email at the centre of Ms Collins' defamation action was sent to her by Ms Boag a few days before ACC referred her friend Bronwyn Pullar's case to the police last month.
It remains a mystery who leaked the email, which Ms Collins forwarded to the ACC's chief executive and chairman.
Ms Pullar is the former National Party insider and ACC claimant who was mistakenly sent details of 6700 other ACC claimants and subsequently went the media about the privacy breach.
