The public believed their personal and credit card data was "significantly at risk".
"Organisations have got to respond to that risk to bring back that confidence level of the people using their services."
People need to use trusted organisations but understand the risks involved, he said.
Most of the recent publicised data breaches were accidental rather than malicious, Mr Griffin said.
"But you can imagine the more and more breaches that become very very public, the lower the confidence is going to be in those organisations."
It wasn't a simple task for organisations to rebuild public confidence, but it needed a "concentrated effort", to achieve the right levels of security, Mr Griffin said.
The survey measured consumer perceptions on a scale of zero to 300, with 300 representing the highest level of perceived concern.
The Unisys Security Index score for New Zealand was 134 out of 300 - down 10 points from 144 recorded in March last year.
The research was conducted in Australia, Belgium, Brazil, Columbia, Germany, Malaysia, Mexico, Netherlands, New Zealand, Spain, the United Kingdom and the United States.
