Director-General of Health Ashley Bloomfield is being warned of major health problems for Canterbury if he can't stop the flurry of resignations of the region's top health executives.
In a matter of days, four senior staff have walked from their positions at Canterbury and West Coast district health boards.
The management team has been at loggerheads with government appointees on the Canterbury DHB board over cost cutting efforts.
Tuesday's shock resignation of longstanding Canterbury DHB chief executive David Meates was compounded on Wednesday when chief financial officer Justine White announced she was moving to the Auckland District Health Board.
The region's planning and funding director Carolyn Gullery also quit this week, while chief people officer Michael Frampton left in July.
Former chair of the Canterbury Hospital Medical Staff Association Ruth Spearing, told RNZ's Anan Zaki that world class talent is leaving Canterbury and Dr Bloomfield needs to step in.
