Waikato businessman Sir William Gallagher is footing the bill for a farewell for outgoing chief executive Mark Flowers.
The private event is being held at the Gallagher Group head office in Kahikatea Drive on Monday 25 March.
Flowers resigned from his role as chief executive last November following controversy around spending and allegations against him.
The 69-year-old has been on sick leave since August and officially left the organisation earlier this month.
Wintec chairman Barry Harris said in February that Wintec was working with Flowers to organise a farewell.
