In a video seen by the Herald, another man came then came and grabbed the chair out from under her, and pulled her by her legs out of the room.
There were even cries of “pull her pants down” as Jakobs was removed from the room.
Jakobs said her phone was thrown on the concrete floor and damaged after she was pulled out of the room.
Jakobs now has bruises all over her body, loose teeth, and is still shaken up by the event.
She said she was shocked by how few people in the room stood up and said something while she was being assaulted.
Julian Batchelor, who organised the event, said the meeting was well-attended.
“It’s tragic when you’ve got protesters trying to cancel free speech like they tried to.”
Security staff had been escorting attendees into the venue to prevent confrontations with protesters outside the building.
Police also encircled Batchelor as he left the building after the event in the face of more than 100 protesters.
The country-wide tour has attracted controversy at multiple stops.
The meeting in Golden Bay earlier this month descended into violence as attendees - including far-right extremist Lee Williams - and protesters clashed.
The controversial tour has resulted in several bookings being cancelled, often at the last minute, while organisers have also struggled to find venues willing to host meetings.
