Bayldon says the research shows why New Zealand needs modern slavery legislation. Currently, he says, it's "very difficult for Kiwis" to find out if products they are looking at purchasing are linked to forced or child labour and many buying goods linked to slavery "unwittingly". Companies are also not required to check their supply chains are contributing to slavery, he says. Bayldon said legislation could require businesses to understand the risks of modern slavery in their puchasing, report on those risks and take action to address them. That would give consumers more information about what they are buying and how it was manufactured.
