Thyroid Association of New Zealand

About Us

The Thyroid Association of New Zealand (TANZi) is a patient-to-patient support group, started in July 2008, using the name New Zealand Thyroid Association. 
We are a voluntary organisation, whose founding members came together when GSK changed their Eltroxin formulation, causing many adverse reactions among users.

We believe that every person has the right to be healthy and symptom-free and the right to a treatment plan that works
for them.  We feel it is time for the medical profession to amend the current protocol regarding the treatment of thyroid disorders, particularly hypothyroidism. To join us, there are no membership fees. 


  • Increase awareness of the prevalence of hypothyroidism, and the difficulties facing patients in obtaining a correct diagnosis and appropriate treatment within the NZ Health system

  • Provide educational and emotional support to patients and their families.

  • Offer information on available treatment options for the general public and the medical profession

  • Provide advocacy on behalf of thyroid disorder sufferers (both hypo and hyper) with government and the medical professions

  • Help encourage people to actively participate in taking control of their own health

  • Pursue the need for open and free access to independent and accurate information both at the time of diagnosis and thereafter

  • See more alternative synthetic T4 medication permanently subsidised by Pharmac and to eventually obtain funding for Whole Thyroid Extract and T3 medication as well.

Why people join TANZi

Sometimes people see several doctors and endocrinologists before they find one who can help them with their symptoms. 
We can help you: 

  • Learn more about thyroid disease signs and symptoms
  • Find a doctor who can diagnose and treat your symptoms 
  • Hear about treatments and lifestyle changes that are work for many people
  • Access resources e.g. books, that patients find helpful.
