The strength of the New Zealand dollar had also been unhelpful, Rowntree said.
He said trading conditions for the company had been tough, especially with the sovereign debt crisis in Europe.
"General market conditions are pretty bad."
Rowntree said most of the staff who had lost their jobs at Flotech had already found new positions elsewhere.
"We've had numerous people wanting our staff - they've been calling continuously wanting [to employ] people."
However, Engineering, Printing and Manufacturing Union (EPMU) assistant director of organising Strachan Crang said the union had 37 members working at Flotech and many had indicated they would have to move to Australia because no jobs were available in this country.
Crang said the Government needed a strategy to ensure manufacturing jobs remained in New Zealand, including monetary policy changes to restrict the strength of the dollar.
