Currently a record number of Kiwis are donating plasma, but it is still not enough.
More than 25,000 people donated last year, but another 4000 are needed just to meet demand.
NZ Blood Service CEO Sam Cliffe joined Heather du Plessis-Allan to discuss the importance of plasma donations.
"Plasma is one of those amazing things that can be made into 11 life-saving products, and we manufacture it into a whole load of different products which can be used to treat kids with immunodeficiency disorders, to clotting disorders, to cancer, liver disease, a whole range of things."
