The Labour leader has defended his newest candidate as someone with the utmost integrity.
Police Minister Mark Mitchell says Rakesh Naidoo has been privy to sensitive information.
It comes as Labour releases its list for candidates for the election.
The late timing of the confirmation sparked criticism from the Police Commissioner.
Naidoo is 13th on Labour's list.
Labour's leader has accused Richard Chambers of 'making a statement that basically has no evidential base' about a superintendent named as a Labour candidate.
OPINION: The scrap over Labour's newest candidate has got very ugly.
