Economic Development Minister Steven Joyce says the Government is addressing the bias that some companies say they encounter when bidding for public contracts.
The complaints feature in a report commissioned by Manufacturing New Zealand, which asked 15 high-growth companies to name things the Government could do to help them.
Mr Joyce admits domestic companies have had problems bidding for government jobs, and says officials have worked over the last three or four years to give domestic companies longer to consider their proposals.
He says officials are also now taking into account the cost of a project over its lifetime, rather than only the initial costs, and that calculation often favours local firms.
And he says he announced on Tuesday that another 19 companies will get research and development growth.
