The United States Trade Representative has called out 54 countries including New Zealand for failing to impose and effectively enforce a ban on imports made with forced labour. It claims US workers are competing globally on an unlevel playing field as a consequence. To address it, the US Trade representative is proposing an additional tariff of 12.5 percent on most New Zealand goods. Meanwhile a Modern Slavery Bill with cross-party support is already making its way through New Zealand's parliament. Sarah Cotgreave is on the board of Transparency International NZ, which has made a submission on the proposed law. She spoke with Lisa Owen.
