From next week, people who lived in Britain, France and the Republic of Ireland during the mad cow disease outbreak of the 1980s and 90s, will be able to give blood.
Restrictions were imposed more than 20 years ago, over concerns about the human variant Creutzfeldt-Jakob disease.
The New Zealand Blood Service has announced they'll be lifted next Thursday, and it's expecting a big influx of new donors.
Its Chief Medical Officer Dr Sarah Morely says they are delighted to open up the restrictions.
Morely spoke to Charlotte Cook.
