The biggest use of blood products in NZ is in cancer treatment. Around 28% of all blood donations are used by cancer patients.
Our Medical Officer will need to review your condition. You may be able to donate and if so, will be able to give frequent donations at 1-4 week intervals to bring your iron overload under control.
Please discuss with our Medical Officer. You should obtain a referral note from your General Practitioner that provides information about the diagnosis, liver function tests and your current iron status, to assist the review.
If your piles / haemorrhoids are not causing symptoms or produce symptoms infrequently, you may donate.
If regular or severe bleeding is present, we ask you to wait for one month after the last episode.

New Zealand Blood Service has height and weight criteria for all first time donors who are under 25 years old.
Find out if you meet the height and weight criteria by using our handy quiz
Explanation: The amount of blood your body contains is proportional to your height and weight. The criteria are based on international best practice which recommends donors give no more than 15% of their total blood volume in any whole blood donation, to ensure the donors’ health is protected.

Hepatitis means inflammation of the liver. It can be caused by infection (such as the viruses hepatitis A, B or C), or by an unknown cause. You cannot donate until 12 months after full recovery.
Hepatitis - my friend or family member has had hepatitis. Can I donate?
This will depend on the type of hepatitis. Please call your local Donor Centre or 0800 GIVE BLOOD (0800 448 325) and ask to speak with a nurse if you need more information.
Hepatitis - my partner has had hepatitis. Can I donate?
You can donate 12 months after your last sexual contact with a person who has hepatitis, or 12 months after the person has fully recovered.
Yes, provided you are not currently suffering an episode with sores. Any recent sores must be clean and dry.
You may donate between episodes.
Deferrals for sexual behaviour are based on what you do or have done and not on sexual orientation.
Since December 2014 the criteria has been: You must not give blood for 12 MONTHS following oral or anal sex with or without a condom with another man (if you are male).
NZ Blood Service has recently done a review on the behavioural donor deferral criteria. The full report can be seen on the website here.

It takes just 24 - 28 hours to replace the volume, but approximately 6 weeks to replace the red blood cells.
A single unit of blood is about 470mL, that's about 8% of your total blood. The body manufactures blood constantly and will soon replace the donated blood without any ill effects.
Every week, we need to collect approx 3,000 whole blood donations to meet the needs of hospital patients and users of blood products throughout New Zealand. That's around 147,000 whole blood units each year.
Donors may donate whole blood up to four times a year with a gap of at least 12 weeks in between donations.
Apheresis donors may donate plasma or platelets every two weeks to a maximum of 23 times per year.
Human T Cell Lymphotrophic Virus.
This virus is rare in NZ but more common in some overseas countries. It can infect some white blood cells and other tissues. The virus sometimes causes a leukaemia or serious deterioration of the spinal cord. A test for this virus infection is carried out on new donors as a precautionary step.
Hypoglycaemia means low blood sugar. There are many reasons for low blood sugar and an important one is from treatment of diabetes. If you have symptoms of hypoglycaemia that is not related to diabetes or other serious illness, you can donate provided that you have eaten properly within 2 hours prior to donating. As with all donors, you should also drink plenty of fluids both before and after donation.
