Customers are paying about $4 a month less for their broadband than they were a year ago, a new Commerce Commission study has found.
This, the commission said, was the result of its 2015 programme to fix the maximum amount lines company Chorus could charge internet providers for its broadband services over local lines.
The commission found that 90 per cent of these price reductions had flowed through to customers.
"Those decisions produced a net decrease of just under $4 per month per customer compared to wholesale prices a year earlier," the commission said.
Telecommunications commissioner Stephen Gale said the organisation was pleased the benefits of the regulation had flowed through to customers.
