Leaving the council was the best decision he had ever made, he said.
"I'd stopped having fun. I now have my life back."
A Northern Advocate request in February for details of his severance payment was declined by the council, despite it having to put the information in its 2011/12 annual report when it is published.
At that time, the council noted it was required to disclose the information in its annual report, but said it needed to protect personal information it may hold about an employee and the need to manage its employee relationships in confidence.
The Advocate had cited public interest in the ratepayer-funded position as a reason for disclosure.
The Advocate asked the Ombudsman to review the council decision and the payments to McKerchar were released by the council this week.
Retired lawyer and Mangawhai ratepayer Clive Boonham said yesterday that many ratepayers in his area considered McKerchar had a key responsibility for the council's major financial problems.
Boonham hoped commissioners who took over the council governance next month would investigate council finances to find out what went wrong.
