Fitzroy Yachts in New Plymouth said in January that it would close - at the cost of 120 jobs - as a result of falling demand.
Berry said the reduction in the workforce reflected "production needs". The company is building a 44.1m motoryacht scheduled for completion at the end of the year.
"It would not be prudent for us to continue to pay our skilled craftsmen when we have no work," Berry said, adding that the firm had helped most of those made redundant find new roles in the marine industry.
She said Alloy Yachts, which has won more than 30 international superyacht awards, was in the fortunate position of being considered one of the world's top superyacht builders. The company was optimistic about proposals it had provided to potential customers, but in the "unlikely event" that a superyacht contract was not signed by September the firm would have to consider more redundancies.
NZ Marine Industry Association executive director Peter Busfield said competitors in the Northern Hemisphere were also receiving government subsidies that allowed them to lower their prices.
Berry questioned why tax breaks were provided to the film industry and not the superyacht sector.
But Minister for Economic Development Steven Joyce said the Government could not subsidise individual struggling companies.
"The Australians have tried doing some of that with their car industry for example and it has become a real problem for their economy which they are now having to deal with," Joyce said.
He said that while the high dollar was challenging for some exporters, it reflected the strength of this country's economy.
