Confirming a public meeting and workshop would be held at Cargills Hotel, at 2pm on Sunday, Dr Nitschke said "the idea you can't have a forum to discuss issues is a little bit worrying".
Dubbed Dr Death by his detractors, Dr Nitschke said apart from Dunedin and Christchurch - where he will hold a workshop on Saturday, he had never experienced problems hiring venues anywhere in the world.

"Right to Life spokesman Ken Orr, of Christchurch, said he was pleased Mr Nitschke was "getting a reaction because that is the reaction he needs to be given".
"I see him as an evangelist for a cult of death."
Right to Life supporters have put pressure on venues where Dr Nitschke will speak, including the Kingsgate in Dunedin and Hotel SO in Christchurch.
"We have expressed our concern, requesting they [hotel managers] give further consideration to hosting his talk," Mr Orr said Kingsgate Hotel management declined to speak to the Otago Daily Times, but one staff member said several calls had been received from people concerned Dr Nitschke would speak at the venue.
The Dunedin hotel cancelled the booking several weeks ago. Despite receiving regular calls, Hotel SO would not cancel the booking in Christchurch.
"We won't cancel because he [Dr Nitschke] is a paying customer," Hotel SO chief executive Nick McCaw said.
Paula Westoby, of Dunedin, chapter leader of Exit International Otago, said finding a venue for Dr Nitschke had been difficult, with some resistance from local hotels.
"It has been frustrating and, as a result, we have not been able to put up the posters with the correct venue until recently."
Despite a request not to use any venue which former member and euthanasia campaigner Lesley Martin had used, Exit International had booked a room at Cargills Hotel, where Ms Martin spoke in March last year.
Ms Martin was convicted in 2004 of attempting to murder her terminally ill mother with an overdose of morphine.
A Cargills Hotel spokeswoman said the hotel became aware about the topic of the workshop only yesterday, and it would not be a problem.
The hotel had received no complaints about the public meeting and workshop, she said.
Holding a public meeting on the topic of voluntary euthanasia, Dr Nitschke will also host a workshop, which is $50 to the public and free for members of Exit International, the assisted suicide organisation he founded.
Dr Nitschke will be selling copies of his book, The Peaceful Pill Handbook, which has been banned in Australia since February 2007 but allowed for sale in New Zealand since May, following a decision by the Office of Film and Literature Classification.
