New Zealand is facing a growing challenge in meeting demand for lifesaving plasma products, with the New Zealand Blood Service calling for an additional 4,000 plasma donors over the next 12 months despite recording its highest-ever donor numbers.
The appeal coincides with National Blood Donor Week and highlights the increasing importance of plasma donations in treating a wide range of serious medical conditions, including immune deficiencies, bleeding disorders, cancer treatments, trauma care and complications arising from major surgery.
According to the New Zealand Blood Service, more than 25,000 New Zealanders donated plasma during the past year, setting a new national record. However, health officials say growing demand means that record participation is still not enough to maintain future supplies.
Plasma is the straw-coloured liquid component of blood that carries proteins, antibodies and clotting factors throughout the body. It is used to manufacture a range of critical medicines relied upon by thousands of patients across New Zealand. Unlike whole blood, plasma can be collected through a specialised process known as plasmapheresis, where plasma is separated and collected while other blood components are returned to the donor.
Health experts say demand for plasma products continues to rise globally due to advances in medicine, population growth and increasing diagnosis of conditions requiring plasma-derived therapies. International blood services have reported similar challenges in maintaining supply levels as demand grows faster than donor recruitment.
For Māori communities, the call for donors carries particular significance.
Māori continue to experience higher rates of many chronic health conditions, including cardiovascular disease, cancer and other illnesses that can require blood and plasma-based treatments. Increasing participation in donation programmes is viewed by many health advocates as another way whānau can contribute directly to the wellbeing of communities across Aotearoa.
The New Zealand Blood Service says every plasma donation has the potential to support multiple patients, with some plasma-derived medicines requiring contributions from hundreds of donors to create a single treatment course.
Officials are particularly encouraging first-time donors to consider making plasma donation part of their regular routine. While many New Zealanders are familiar with blood donation, awareness of plasma donation remains lower despite its growing importance to modern healthcare.
The organisation says maintaining a sustainable donor base is critical to ensuring hospitals and healthcare providers can continue accessing the products patients depend on every day.
As demand continues to climb, the challenge for New Zealand will be turning record donor numbers into even greater community participation.
For thousands of patients relying on plasma-derived medicines, the message from health officials is simple: more donors are needed, and every donation can help save lives.
