The amount of these damages was not set at the time of the original decision in 2013 and Greymouth, Sturgess and his company came back to argue the matter in February.
Greymouth sought about $830,000 from the former director.
The bulk of this was related to a fracking operation at a Taranaki well at Sturgess' direction.
During this time, the well was not producing any gas and there were limited prospects of finding producible hydrocarbons.
Sturgess did not consult his fellow board members before proceeding with the operation and Judge Gilbert found the decision to proceed was negligent.
Sturgess and his company were found liable for the cost of the operation, less what would have been spent if a recommended mini-frac had gone ahead instead.
It was estimated by the engineer who recommended it that this mini-frac would have cost US$20,000 ($27,250).
The full-frac which Sturgess directed instead cost $733,000, according to Greymouth.
Sturgess claimed the mini-frac was "fatally flawed".
In his calculations, the judge set the costs of the full frac at $700,000 and the cost of the recommended mini-frac at $50,000.
He therefore awarded damages to Greymouth of $650,000.
In respect of a separate seismic programme Justice Gilbert set the damages at $129,630.
