World Blood Donor Day
History
The World Health Organisation and the International Federation of Red Cross and Red Crescent Societies initiated World Blood Donor Day (WBDD) in 2004. It takes place on June 14 each year and provides an opportunity for a united, national and global celebration on a day that has particular significance; the birthday of Karl Landsteiner, the Nobel Prize winner who discovered the ABO blood group system.
World Blood Donor Day - a chance to thank donors
On World Blood Donor Day, we want to say thank you to New Zealand's 110,000 unsung heroes, and encourage more people to follow their lead.
There is no substitute for donated blood and the NZ Blood Service has a constant need to recruit new donors. We need to collect 3,000 donations nationally each week to meet medical demands, and must work continuously to renew the donor database at a rate of more than 20,000 people per year.
New Zealand Blood Service celebrates World Blood Donor Day on 14th June each year in each of its Donor Centres around the country.
Thank you to all of the wonderful blood donors around New Zealand!
