New South Wales Police has admitted all records of a senior officer's involvement with a key Catholic Church body set up to deal with sexual abuse cases have been shredded.

This includes briefing papers and all documentation over a five-year period from 1998 to 2003.

The revelations come from Freedom of Information (FOI) documents obtained by the ABC's Lateline program.

The top level group established by the Catholic Church's bishops is known as the Professional Standards Resource Group (PSRG).

It was created in 1997 in response to the Wood Royal Commission into the police and paedophilia, and its key function was to advise the church on specific cases involving clergy and others.

Earlier this year, a NSW Police spokesman told Lateline all the information provided by the church to the serving officer was anonymous.

The names of the victims and the priests had been removed, allegedly at the request of victims who the church said did not want police involvement.

The documents revealed on Lateline were lodged by NSW Greens MLC, David Shoebridge.

They reveal that Inspector Beth Cullen, who was then a senior sergeant with the Sex Crimes Unit, shredded all documents pertaining to her role with the PSRG from 1998 to 2003.
