The minimum weight is 50kg for whole blood donation, however first time donors must also meet height and weight criteria. The criteria are based on international best practice which recommends donors give no more than 15% of their total blood volume in any whole blood donation, to ensure the donor’s health is protected.
The amount of blood your body contains is proportional to your weight: heavier people have a larger volume of blood. If a standard donation of 470mL plus test samples is too large a proportion of your blood volume, you will be unable to donate.

Apheresis: (Plasma or Platelet donors)
We will not normally accept new apheresis (plasma or platelet) donors who weigh less than 58kg, unless the donor has a special antibody that is needed to make a special treatment product.
These criteria are in place to protect your health as a donor. If your weight becomes acceptable for blood donation at any time you can be accepted as a blood donor.

Less than 4% of New Zealanders donate each year, yet over 27,000 of us need blood each year. This means that fewer than 4% of the people in our communities are supporting 100% of our blood needs.
Anyone in need, anywhere in the country. People such as accident victims, patients undergoing surgery, recipients of organ and bone marrow transplants and those undergoing treatment for leukaemia. You can be sure that no matter who receives it, he or she will be very grateful. See here
Back at the laboratory the blood is filtered to remove the white blood cells. It is then spun in a centrifuge and separated to make different blood components. These are red cells, plasma and platelets. In addition, the filter removes the white cells. The four bags are needed at different stages of these processing steps.
