An estimated 828 million single-use plastic bottles are thrown away per year in NZ, reports Auckland Council. If we each used a refillable bottle just 1 in 3 times instead, we’d save around 257 million plastic bottles a year, according to RefillNZ. Almost every block in the Auckland city centre has a water fountain or a place that will refill your water bottle for free. All the public drinking fountains in Auckland and nearly 200 cafes and council facilities are on the RefillNZ website and app.
