The Flower Study

This is a study to trial a new flower extract in men with pre-diabetes to see if it lowers blood glucose levels. It requires 4 visits to Wellington Regional Hospital for 3 hours each time. You may be eligible if you are:

  • male
  • aged between 18 and 65
  • have pre-diabetes (HbA1c 41-49).


This is a study for men and women with pre-diabetes, being run in collaboration with the University of Otago. It aims to see whether probiotics and cereals can prevent diabetes. For more information and a sign-up form, visit the study website at


The purpose of this study is to trial a medical device that delivers a one-off low-level radiofrequency energy through the wall of the blood vessel to the liver to disrupt the nerves that lead to the liver. Previous research has shown that disrupting these nerves may lead to a lowering of blood sugar levels in people with type 2 diabetes. This procedure may be useful for people who have trouble controlling their blood glucose levels.

You may be eligible if you:

  • are aged over 18 years
  • have type 2 diabetes
  • need help with blood sugar control.

Fidelio and Figaro

We are looking for people to take part in a clinical trial for people with Type 2 Diabetes who have raised protein in the urine. This is a trial of a tablet to reduce the damage done to kidneys and heart by diabetes. There are two arms to this study, one looking at protecting the kidneys (Fidelio) and one looking at protecting the heart (Figaro).


Trialnet is a continuously running screening study for blood relatives of people with type 1 diabetes, using antibodies to help researchers understand and predict the risk and development of type 1 diabetes.

You or your child may be eligible if a parent or sibling has type 1 diabetes.

Previous studies

Changes in DNA methylation in people with type-2 diabetes over a period of weight loss

This project uses stored blood samples from previous weight loss studies. Given the importance of genes in complex disease, and the key role these mechanisms play in the interaction between environmental influences and genetics we are investigating whether DNA methylation changes over time with dietary intervention and associated weight-loss.

The Garden to Table Evaluation

The Garden to Table organisation introduces vegetable gardening and cooking into New Zealand primary schools. This project aims to evaluate the programme in four low decile Wellington schools to ascertain whether it improves the nutritional quality of children’s diets, nutrition knowledge and willingness to try new foods.

Thanks to Pub Charity for funding this project.
