A mobile unit would visit him and his colleagues at work when they would all donate together.
The family then moved around a bit and stopped donating for a while but soon found their feet in the Waikato and became regular donors again in 2003.
Mr Daniels said that was where he first saw platelets and plasma donated, and enquired if he could donate that instead of whole blood.
Plasma is used to treat burn victims, people who have lost a lot of blood, kidney patients and chemotherapy patients.
The only reason Mr Daniels would not donate now would be because was he was unwell, or too old.
"If you can do it and you are capable of doing it, the only reason you wouldn't is you're selfish.
"Where else can I get a free blood test and blood pressure checks every three weeks. Not only that they bring you tea and coffee or whatever. Crackers and cheese and you finish off with bakery if you go in on a Thursday."
Mr Daniels said he, his family and friends have never needed a blood transfusion.
"We are the four per cent that supplies that 80 per cent."
He heads down to the Tauranga Donor Centre every three weeks to make a plasma donation.
