Winton, a New Zealand-listed property development company, is undergoing significant leadership changes with the announcement that Chief Financial Officer Jean McMahon will depart the firm in November. McMahon’s resignation comes just one day after the company’s chairman, Steven Joyce, and director Guy Fergusson revealed their intentions to step down, marking a further shake-up in the company’s executive ranks.

The company did not provide a reason for McMahon’s decision to leave after eight years with Winton. Joyce praised McMahon for her financial expertise and professionalism, noting her valued contribution to the senior leadership team since 2018. Winton indicated it will initiate an external search for a new CFO and will update the market once a replacement has been secured.

Joyce and Fergusson cited a “fundamental misalignment” with majority shareholder and former chief executive Chris Meehan as the driver behind their resignations. Joyce is scheduled to leave on Monday. Meehan, who holds a 55 percent stake in Winton alongside his wife Michaela, declined to comment on the recent departures.

The trio’s resignations follow Meehan’s abrupt resignation as chair and CEO last month amid reports of multiple personal grievances and staff complaints alleging aggressive behaviour. Earlier in the year, in March 2026, the Employment Relations Authority ruled in favour of Leah McCann, Meehan’s former executive assistant, ordering Winton to pay over NZD 100,000 in lost wages, compensation, and penalties linked to her treatment at the company. McCann’s case included allegations related to Meehan’s conduct towards her over a business-class flight upgrade.

In a July statement to the NZX, Winton clarified that Meehan’s resignation occurred during the final stages of a board-led employment process unrelated to the company’s financial performance or reporting. The statement also noted Meehan had taken leave for health reasons prior to his departure. Although no longer chair or CEO, Meehan remains a director and will consult on major development projects as needed.

The company faces ongoing instability as it searches for new leadership while addressing internal challenges stemming from the recent controversies involving its former chief executive.
