Health Minister Minister Tony Ryall says the Budget will include a significant boost in services to address growing rates of diabetes.
Medical specialists say rising numbers of people with diabetes could cripple the health system. Some 225,000 people in New Zealand are known to have it.
But the Society for the Study of Diabetes says the numbers are rising rapidly and could eventually overwhelm progress in identification and management of the chronic disease.
Mr Ryall said the Budget on 16 May would provide a significant boost for services and address risk factors.
He said the extra funding will go to measures that have worked, such as Green Prescriptions, which is advice for patients to be physically active.
