A $100,000 pay rise for NSW Police Commissioner Andrew Scipione has been criticised by the NSW Greens, who say the state's cop has been caught out in a classic case of "doing as I say, not what I do".

Mr Scipione has negotiated a 20 per cent pay increase with the state government as part of his agreement to stay on as commissioner for up to two more years.

Last financial year Mr Scipione's remuneration package was $497,000. The pay rise, which is still to go through the statutory remuneration tribunal, will take his pay package to almost $600,000 a year.

That salary is less than the $634,880 paid to the Australian Federal Police commissioner and the $691,200 paid to the head of the newly created Border Force.
