PGG Wrightson says current chair Joo Hai Lee will step down before June 28 but that the board will continue its governance review in the meantime.
Lee represents Wrightson's former majority shareholder, Singapore-registered Agria, and took over as chair in early November after Agria principal Alan Lai abruptly resigned the day before the scheduled annual shareholders' meeting.
Wrightson says in a statement that the board "will provide an update in the near future regarding the outcomes of the review and the chair's appointment."
Agria now owns 46.6 percent of Wrightson after it was forced to sell down its previous 50.2 percent stake by the Overseas Investment Office. That was achieved by unwinding Ngai Tahu's stake in a joint venture with Agria, with the iwi now owning 3.6 percent of Wrightson in its own right.
Bruce Irvine, chair of Wrightson's independent directors, says his committee "has continued to monitor matters relating to the OIO investigation and settlement and assess implications for PGW."
