Dr Titchener's service uses Patient-centred Care, an approach that educates patients about choices available for diabetes management.
By understanding treatment options, patients could choose a management regime best suited to their lifestyle.
Dr Titchener said the approach empowered patients through education. By participating in management decisions, patients were more likely to adhere to a treatment regime than to follow a one-size-fits-all approach.
To counter the claim it is too expensive, she has cited studies that show her service saves the DHB money in the long term, due to continuing patient health.
Businessman Mr Lowe was moved to be the primary backer of Putting Patients First after his employees recounted how the service had transformed lives.
"The DHB is taking away a crucial health service, a service that is changing patients' lives, delivering outstanding long-term health outcomes, closing the inequality gap for Maori, and saving up to 74 per cent for each patient's treatment," he said.
Dr Titchener won an Eli Lilly Award for her contribution to diabetes care in 2010.
The meeting is at Te Aranga Marae in Flaxmere at 6.30pm on Monday.
