He said with the long delay to get the project off the ground it had increased the project cost.
"The cost has increased by 50 percent," O'Neill said in Madang this afternoon.
He said that with the increase in cost it meant benefits to the National Government and landowners would be delayed.
When the project was signed between the State and Exim Bank of China in 2011 it showed phase one would cost US $95 million.
Meanwhile two landowner group leaders who were against the project, delaying it through court battles, demonstrated their regrets with pigs presented to the government leaders and investors at the project site in Vidar.
Frank Don and Francis Gem led their people as they brought pigs and garden food to the occasion to show their apology.
