We're supporting Ecomailbox, a nationwide scheme to reduce the amount of junk mail that goes in letterboxes.
Ecomailbox provides residents with a 'No Ad Mail' letter box sticker, suitable for all surfaces and weather conditions.
Residents who use the sticker on their letter box will no longer received paper circulars, but will still be able to view the information online at the Ecomailbox website.
Having the sticker on your letterbox will not stop you from receiving local newspapers and newsletters.
The stickers are free and can be picked up from the Council offices in Fairlie and Twizel and the Information Centre in Lake Tekapo, or ordered from the Ecomailbox website.
Ecomailbox estimates that 30kg of advertising circulars are delivered to each New Zealand home every year. The paper used to print these comes from close to 300,000 trees.
