This was arranged and in April of last year Duncan was suspended while the board investigated whether he had misappropriated company funds.
He resigned later that month.
Duncan took a case to the ERA saying he was entitled to the bonus and wanted orders for it to be paid. He also sought redundancy entitlements and a penalty for a late payment of holiday pay as well as interest.
In August 2011 there were discussions between directors about the bonus. Duncan believes it was agreed he would receive two million PGC shares for the year ending June 30, 2011.
Another PGC director, Bryan Mogridge, disagreed and claimed the PGC board proposed the bonus but that it needed sign-off from the remuneration committee.
Authority member Tania Tetitaha said in a decision on the case this week that Duncan had no legal entitlement to the two million bonus shares, which PGC estimates would be worth around $880,000 today.
She also dismissed his claim for redundancy compensation.
Duncan had originally sought $13,930 of holiday pay arrears, which PGC paid after the ERA hearing. Duncan then sought interest and a penalty for the late payment, which the ERA awarded in its decision this week.
PGC estimates this to be about $4,000.
