Watercare chief executive Mark Ford is expected to step down shortly for health reasons.
Last night, chairman David Clarke said the Watercare board would consider Mr Ford's situation on Friday before making a public statement.
Mr Ford, who keeps a low public profile and is known as "The Fixer", has led Watercare since 1994 apart from an 18-month stint heading the agency that set up the Super City structure.
He returned to Watercare in 2010, became the first chairman of Auckland Transport and was appointed by the Government to chair Solid Energy. He retired from that role in March this year for health reasons.
Remuneration figures released by the council this week show Mr Ford is the highest-paid bureaucrat in Auckland. His salary and bonus packages have increased by 21 per cent in two years, from $710,000 to $860,000.
