Wealthy Waikato-headquartered Tainui Group Holdings is hunting for a new chief executive after Mike Pohio resigned to pursue governance opportunities.
Chairman Sir Henry van der Heyden said Pohio had been eight years at the helm and had seen assets grow by $500 million.
Last year, Waikato-Tainui declared its asset base had risen from $925.1 million to $1.06 billion.
The business is now poised to embark on its biggest venture yet - the controversial $3.3 billion freight hub or inland port scheme at Ruakura.
Waikato Tainui got that Ruakura land in a Treaty of Waitangi settlement and has been wanting to develop about 500ha in partnership with Chedworth, owning an adjacent 116ha.
