Tickets for the Okere Falls Store Beerfest are selling out quickly, with Saturday night already booked out.
The popular annual event began on Monday and runs until Sunday.
Okere Falls Store owners Andi and Sarah Uhl have been running the Beerfest for the past five or six years. They had wanted to bring a new concept to Rotorua, Mr Uhl said.
"It's something different, we have both obviously been to the real Oktoberfest in Munich. We didn't just want to recreate the festival here, but thought it would be a great way to contribute to the community," he said.
Mr Uhl grew up 80km south-west of Munich and said the city's beerfest was a huge part of local culture.
