New World, Pak’n Save and Four Square supermarkets will be microbead-free from July 1.
That is a year ahead of the Government’s proposed date for a microbead ban.
The beads, which are used as exfoliating agents in skin care products and toothpastes, are a threat to marine life.
A single tube of microbead face wash can contain more than 300,000 beads. Most end up washed through water filtration systems and into the sea, where they are being ingested by marine animals.
About 100 personal care products in New Zealand have microbeads. It’s estimated about 10,000 tonnes a year of plastic microbeads are used globally.
