I was on the Health Committee that heard the submitters to this bill I was very, very pleased that the oral health clinical leader and deputy chief medical officer of the Southern DHB, Tim Mackay, was one of the submitters who spoke very, very strongly as an advocate for fluoride being added to drinking water. I've known Tim for many years, he has operated on our youngest daughter, who has a disability and is a frequent user of the DHB dental services. Tim and I have spoken often about how difficult it is for the patients he sees and how heartbreaking it is for someone like him to seem many of these patients.
