The working group was formed to provide recommendations on how New Zealand might better use and treat older workers.
BusinessNZ Chief Executive Kirk Hope said more people were choosing to work beyond the age of superannuation, to the benefit of the economy.
"Research shows that more workers working longer can add significantly to a country’s economic growth.
"Senior workers can play a valuable part in addressing New Zealand’s skill shortages but changes are needed for this to happen."
The white paper recommends that businesses give older candidates more consideration for jobs and training, and view older workers as a resource rather than a problem.
It also recommends improved coordination between Government agencies responsible for older workers and senior issues.
"BusinessNZ supports a national strategy to improve ageing workforce results," Mr Hope said.
