Until October 2015, councils and businesses in New Zealand had used a variety of colours to indicate what items can be recycled in what bins. This created confusion when colours were used inconsistently and increased the likelihood of contamination. In October 2015 WasteMINZ, the Glass Packaging Forum and councils around New Zealand agreed on a standardised set of colours for mobile recycling and rubbish bins, crates and internal office bins. Companies wishing to implement nationwide recycling schemes are strongly encouraged to use these colours both for their bins and also on their signage. This will ensure that the colours used are consistent with both public place recycling and household recycling.
