Consumer NZ tested 46 laundry detergents and found that three were no better than washing with only water, but some New Zealand-owned brands fared well.
Shotz Laundry Liquid and EcoLiving Laundry Detergent Sheets with lavender scent scored a very low 27 out of 100, the same points level given to washing with only water. Re-Stor Laundry Detergent Sheets fresh linen scent, a product sold at Woolworths, fared even worse under the Consumer NZ testing.
