"We said we've got to do something about this, the Lions tour is the perfect time to try beat the record."
Mr Tuckey encouraged people to get along "nice and early" to ensure there was enough time to get everyone in place, with the official haka arena opening at 10.30am.
"11am is the gathering time. The attempt will be at midday. People need to take it seriously and make sure you know the actions in sequence. We need the group doing the haka for a period of time to set the record, it's a logistical challenge to set the record."
In order to calculate the amount of people present, each of the participants will be scanned in, Mr Tuckey said.
"Each person is to grab a ticket, which will be scanned. There will also be people doing the count in as people enter through a controlled point."
Mr Tuckey said sufficient evidence had to be submitted to the Guinness World Records.
"The collection of the evidence has to be methodical and we will have a team tomorrow who will be filming, taking photos and counting."
The haka will be led by Wetini Mitai-Ngatai and Eraia Keil, with help from students from Rotorua Boys' High School and Rotorua Girls' High School.
The words to the famous Ngati Toa Rangatira haka, Ka Mate, will be shown on the large screen.
The Bay of Plenty Steamers rugby team will be there from 10.30am to 11am for a public meet and greet.
"As well there will be several ex-Maori All Blacks taking part in the haka which will be cool," Mr Tuckey said.
The International Rugby Club has been co-ordinating with the Rotorua Lakes Council.
Martin Croft, the council's major events co-ordinator, said the giant haka was one of the most interesting events he had worked on.
"Local schools have embraced it and have been practising to be ready for the day."
The event had caught the imagination of the public, Mr Croft said.
"Rotorua Boys' High School and Rotorua Girls' High School have done a lot to promote the event. It highlights that the event is for everyone to be part of."
The event is free to take part in, but a gold coin will be asked for, with all money raised going towards the Starship Foundation who are the official charity partner of the Lions Series.
