The 2013 comments earned Adamson a public rebuke from the chairman at the time, Ralph Waters.
The Fletcher board is chaired by one of New Zealand's most respected business leaders, Ralph Norris, a former chief executive at Commonwealth Bank of Australia and chairman at Contact Energy. Other big names on the board include Tony Carter, who chairs Air New Zealand and Fisher & Paykel Healthcare and is a director of the New Zealand arm of Australia & New Zealand Banking Group; and John Judge, currently chair of ANZ Bank in New Zealand.
"The removal of many experienced senior managers and the reliance on construction work being almost entirely subcontracted has created problems and imbalances that may take years to fully address.
"These were entirely foreseeable and NZSA raised cultural issues with the board in 2016," he said. The association had also taken "credible information" to Norris after the first downgrade this year to suggest the $110 million estimate should be more like $230m.
"Sadly, what we said to the company then and since has come to pass," said Midgley.
"Just days before the most recent downgrade, NZSA had met Adamson and other executives, but the increasing concerns we had were never communicated to the chairman. The former CEO's response that the problems preceded his appointment five years ago, and that he had since put proper provisions and high quality staff in place, are hard to accept given that he personally signed a number of the larger contracts.
"Even if true, it demonstrates that the response was far too little and far too late," said Midgley.
Despite assurances to shareholders that the construction division was a small part of the company, it was the public face of Fletcher Building and was causing the company serious reputation damage at the same time as creating "a $2 billion hole which impacts not only on shareholders, but also KiwiSavers and many other managed funds investors".
Fletcher Building shares were trading mid-afternoon today at $7.71, up 1.3 per cent on yesterday's close and well above the $7.38 low point hit during intra-day trading on July 20, when the downgrade and Adamson's departure were both announced. For the year to date, the shares have fallen 28 per cent.
In the latest downgrade, Fletcher said operating earnings in the year ended June 30 were about $525m, down from $682m in 2016 and below the $610m-to-$650m range the company gave in March, itself a 15 per cent downgrade against earlier guidance.
A spokeswoman for Fletcher said the company had no comment to make at this time.
