Aotearoa needs about 38,000 more blood donors in the next year just to keep up with demand, Stuff reveals. About 110,000 Kiwis donate blood every year, but that is less than 4% of the eligible population. For some Kiwis, access to blood products is life-saving. Rachel Birdling and her friend Wendy, both cancer survivors, reckon it took donations from 432 people to keep them alive while they were ill with leukaemia. The New Zealand Blood Service is hopes its National Blood Donor Week – which runs from June 13 to 19 – will encourage more Kiwis to give blood.
