The drive is on to get former blood donors back in the loop for World Blood Donor Day this Friday.
Former donors are encouraged to get in touch with the New Zealand Blood Service Auckland as part of the celebrations.
Auckland area manager Cheryle Dyson says when people change address or phone number they often forget about donating blood.
World Blood Donor Day celebrations will be held at the New Zealand Blood Service, 71 Great South Rd with a sausage sizzle from 11am on Friday.
