David Darrow, the premier's deputy minister, was asked by the premier to oversee the rebuild of the schooner earlier this year.
Darrow is scheduled to appear before the public accounts committee later today.
He has said that a hydraulic steering system was needed to ensure sailors could control the 3,200-kilogram rudder, work that would cost about $300,000.
Darrow was handed responsibility for the file after a series of cost overruns and delays that has put the restoration two years behind schedule and close to $5 million over budget.
At the project's outset in 2009, the provincial government estimated it would cost $14.4 million, but that had risen to $19 million as of June.
Nova Scotia's auditor general is also conducting a review of the restoration.
