With far fewer letters being sent these days, changes have been made to cover “significant loss revenue” (video first published in 2018).

Sending mail in New Zealand is set to get more expensive.

NZ Post said the cost of sending letters, domestic parcels, couriers and international inbound and international outbound letters and parcels would all rise from July 1 this year.

Sending a letter in New Zealand would increase in cost from $1 to $1.20 20 cent to cover "significant loss of revenue" as a result of fewer letters being sent, it said.

MARTIN DE RUYTER/STUFF It's not just letters that will get more expensive to post. Domestic parcels, courier, international inbound and international outbound letters and parcels would also cost more.

The state-owned enterprise was also making changes to postal products for business customers with the cost of "bulk mail" increasing.

"These changes will assist NZ Post to manage the significant loss of revenue from fewer letters being sent and still maintain a network of more than 880 postal outlets and 1.98 million delivery points," NZ Post said in a statement.

Sending parcels within New Zealand would be 50 cents more expensive.

The number of bulk mail products would be reduced from nine to four.

NZ Post chief marketing officer Bryan Dobson said it had to adjust the prices to provide a commercially sustainable letters service.

"Our postal pricing will now better reflect the cost to process and deliver items, and will help ensure our letters business is in good shape for the future".
