"The trading result for 2011 will not be pretty," chairman Colin Giffney said in a letter to shareholders.
"Significant reductions we have made in employee numbers and operating expenditures will begin to flow in 2012" and will help the company return to profit, he said.
This year's bottom-line loss might not be as bad as feared if Renaissance's $2 million of insurance claims are successful, though the level of recovery is uncertain.
In the past 12 months, Renaissance has had to contend with the Canterbury quakes, while iPod and Mac manufacturer Apple started using a second distributer in New Zealand.
Renaissance is more upbeat about revenue, which is forecast to fall 11 per cent to $185.3 million in the 2011 financial year, while bouncing back to $196.8 million next year.
The shares were unchanged at $1.32 in trading today, and have slumped 52 per cent this year.
