The liquidator of a string of failed Mad Butcher franchisees says he stands by his views the franchise's business model is "flawed".

There have been more than 20 outlet liquidations. Five franchisees have been liquidated since 2017. The numbers do not include stores that have closed at the end of franchise agreements.

Last week, Mad Butcher Northcote closed its doors. Outlets in Albany, Glen Innes and Whangārei have also closed this year.
