The Independent Police Conduct Authority has reportedly received a complaint
about the police investigation into National MP Todd Barclay.
Police last week re-opened their investigation into allegations the Clutha-Southland MP secretly recorded staff in his Gore electorate office, claims that ultimately led to him announcing he would leave politics in September.
The original investigation was dropped after 10 months with officers citing a lack of evidence for a successful prosecution.
The IPCA is understood to have received a complaint from someone not directly involved in the investigation, according to RNZ.
Prime Minister Bill English told reporters on Tuesday that he had told Mr Barclay to co-operate with the police investigation, but had not spoken to him since he announced his retirement to confirm whether he would.
Mr Barclay initially said he would co-operate with the original investigation, but later declined to be interviewed by police on advice from his lawyers.
