Paying blood plasma donors in New Zealand would ensure enough is in the country to meet patients' needs. In Alberta, Canada, donors receive up $105 NZD ($65 USD) per donation. Georgetown University's Professor Peter Jaworski is an expert in the economics and ethics of blood and plasma donation, and co-author of the new report, 'Liquid Gold: New Zealand's need for compensated plasma collections'. He says we should follow Canada's lead in paying our donors, incentivising plasma donation and localising our life-saving resources. Professor Jaworski spoke with Ingrid Hipkiss.
