Postal deliveries may be cut to three days a week under a plan put forward by New Zealand Post to ensure the company remains viable.
Communications Minister Amy Adams released a proposal from the national postal service today to allow "greater flexibility" in its services due to falling mail volumes.
NZ Post wants to change its universal service obligations, signed in 1998, which require it to deliver mail six days a week.
It wants to reduce the number of mail delivery days to a minimum of three days a week, and introducing more self-service kiosks.
Any changes would require Government approval, and the public has a chance to comment on the proposals.
"In deciding whether to accept or reject the proposal or seek to negotiate a compromise, I will look to balance the interests of postal users with the need to ensure a financially-viable postal service," says Ms Adams.
Last April, NZ Post chairman Michael Cullen wrote to State Owned Enterprises Minister Tony Ryall warning that steps to make "fundamental changes to our operational models" needed to take place to cut costs, or delivery days may have to be axed.
