Age Concern says charging four dollars per printed statement sent out feels like a tax on old people.
Kiwi Bank has increased its fees for mailing out statements to promote online use. The fee has gone from free to four dollars to cover printing and postage costs.
Chief Executive of Age Concern Canterbury, Simon Templeton, says increases like this aren't fair on fixed income earners.
"It's disappointing I think, for those people who don't have access to computers or don't feel comfortable - certainly doing banking online".
Templeton says it's too early to focus solely on online as groups of people are being penalised because they are still catching up with technology.
