Jersey health boss was given £129,000 when he resigned
Mike Pollard resigned from his post in 2009 for personal reasons.
Senator Gorst revealed in February that former chief executive of the States Bill Ogley received more than £500,000 when he resigned.
Jersey's auditor general is to review the payments given to civil servants when they leave their jobs.
Christopher Swinson's report will look at how big these payments were and how many have been paid out.
The chief minister said he welcomed the investigation into payments and would wait for it to be completed before finalising new severance guidelines.
