In November, Marshall heard from six families as part of an ongoing investigation into the cause and circumstances of the deaths and whether the brand change affected seizure control.
The deceased include Ricky Blackler, a 24-year-old scaffolder, Reuben Brown, a 27-year-old farmer, 35-year-old Krystal Loye, sales representative Andre Maddock, 31, student William Oliver, 26, and Jessica Reid, a 23-year-old animal groomer at a pet store.
Epilepsy is a common disorder in which nerve cell activity in the brain is disturbed, causing seizures.
It affects about 1-2 in 100 New Zealanders.
