The battle over leasehold ground rents around Auckland's Quay Park galvanised some of New Zealand's top valuation and legal experts.
Ngati Whatua engaged commercial barrister Liam McEntegart, formerly of Simpson Grierson, along with expert valuers Reid Quinlan of Segars & Partners and Sean Molloy of Extensor.
The leaseholders engaged Iain Gribble, a director of valuation business Gribble Churton Taylor and an Institute of Valuers' past president. He has more than 40 years' experience in Auckland, Wellington, New Plymouth and Invercargill and specialises in work relating to the Public Works Act.
Gribble said the scale and number of properties in cases, which ran separately, were large.
"There were seven properties that needed decisions around the same time - two from the first arbitration and five from the second," he said.
