"We are very fortunate to have him here," a spokesperson for the local End of Choice branch said, adding all were welcome to attend.
The meeting comes at a time when ACT leader David Seymour is also pursuing the issue, having prepared a private member's End of Life Choice Bill.
"The intention of the bill is to allow people with a grievous and irremediable medical condition to obtain medical assistance to die if they so choose," Mr Seymour has said.
In a University of Auckland research survey published in the New Zealand Medical Journal earlier this year the majority of those surveyed supported assisted dying for people with painful terminal conditions.
Two thirds of the nearly 16,000 surveyed were in favour.
Dr Bernheim has speaking engagements planned around the country until June 17.
The Napier meeting will be at 10am at Lecture Theatre 1 at the EIT in Taradale, with the local organisers asking for a koha or donation as entry.
