Low iron in New Zealand: signs, testing and next steps

Iron deficiency is one of the most common nutritional shortfalls in New Zealand, and it can creep up slowly. Because the symptoms are easy to brush off, many people live with low iron for months before getting it checked.

Signs that can point to low iron

Low iron affects people differently, but some patterns come up again and again. None of these are proof of iron deficiency on their own — only a blood test can confirm it — but they are worth paying attention to.

• Persistent tiredness and low energy
• Feeling short of breath doing things that used to be easy
• Looking unusually pale
• Brittle nails, or hair shedding more than usual
• Headaches, dizziness, or cold hands and feet

Getting tested

If any of this sounds familiar, the first step is a visit to your GP. A simple blood test measures your ferritin (your iron stores) and your haemoglobin. This matters because tiredness has many possible causes, and treating the right one makes all the difference.

Where iron infusions fit

For some people with confirmed iron deficiency, an iron infusion is an option — particularly when iron tablets have not worked or are not well tolerated. Iron infusions are a prescription medicine and are only provided after clinical assessment. We have a dedicated page explaining how this works in New Zealand, including how PHARMAC funding applies.
