The Centre for Endocrine, Diabetes and Obesity Research (CEDOR) is a specialist research unit based in the Endocrine and Diabetes Service at Wellington Regional Hospital. The unit, which is led by Principal Investigator, Professor Jeremy Krebs, was established in 1998, and has grown to encompass 11 permanent staff members with input from clinical staff from both Endocrine and Diabetes specialities. The unit also supervises students, both MSc and PhD, offers periodic summer studentships and helps with the training of senior medical staff.

CEDOR conducts a broad range of clinical trials looking at both new medications for Type 1 and 2 Diabetes as well as the effects of diet and lifestyle choices and surgery for obesity on health. Investigator-led research is a strong focus for us, with Prof. Krebs having been awarded several HRC grants.

CEDOR also has a long established involvement in Phase 3 and 4 pharmaceutical trials for diabetes. Involvement in all our trials provides people with close medical supervision by our experienced and friendly team of doctors and nurses. Our researchers publish articles and studies in scientific journals and present at conferences in NZ and overseas.

CEDOR conducts research in the following areas:


  • Iodine, Sodium
  • Blood Pressure
  • Acromegaly
  • PCOS


  • Dietary interventions in type 1 and type 2 diabetes
