Most major retailers are signatories of a voluntary Code of Practice:
For more info about where advertising material should be left, visit the code of practice website.
Contact the Distribution Standards Board on 1800 676 136 or email@example.com.
Pick up the phone, call the company, and ask to speak to the manager. Suggest that they ask their distributor to desist putting material in letterboxes with No Advertising Material stickers. Point out that receiving material in spite of your sticker makes you think badly of the company, and less likely to use their services/buy their product.
By law material must be placed in a letterbox (or under your door). It is illegal to place it on a wall, a pathway, doorstep, or poked through a fence (just to name a few examples) and constitutes a litter offence under the Protection of the Environment Operations Act 1997.
Keep the material and call your local council, police station, the Environment Protection Authority or National Parks and Wildlife Service.
You will need to contact them direct – contact details can usually be found near the "contents" section of the publication.
