"But we are looking at around 80 to 90 per cent capacity right now and this is very healthy for the local economy."
He said tourists from the United Kingdom often spent well while on holiday.
"They love all the activities, dining and drinking and generally have a really good time.
"It's all good for us, but I don't think we'll see people living on the streets, so June will be a strong month for us in 2017."
Owner of the Rotorua TOP 10 Holiday Park and chairwoman of Rotorua Holiday Accommodation Parks New Zealand, Jasmine Adams, said all of Rotorua's holiday parks were preparing for the tour.
"The majority of our rooms are fully booked already, but we do have tent sites available and we expect them to be sold out by them.
"It's our quietest period for our sector so it's awesome to have a big event in the middle of that time."
Mrs Adams said most of the bookings were for two or three days and she and husband Jared said they expected "the same madness" that happened last time the Lions were here.
They said a large group of Lions fans had booked all of their rooms more than a year ago.
Rotorua Association of Motels chairman Mike Gallagher said his sites were almost fully booked for the tour.
"We are due to have a meeting about this in February, so I'm not really sure how busy everyone else will be."
He said everyone was looking forward to a mid-winter boost and Rotorua needed to be prepared and ready to promote the city so tourists come to stay either side of the big match.
"A lot of people from the UK will be making this a trip of a lifetime and have been saving for it for years."
According to New Zealand Rugby head of public affairs Ian Long only general admission tickets are available for the Rotorua match with all category A and B tickets sold out.
Destination Rotorua chief executive Michelle Templer said there was a lot of excitement building for the "unofficial fourth test here in Rotorua".
"It's positive to hear that some of Rotorua's accommodation providers are starting to reach capacity, but we want to assure people that there is still accommodation available in Rotorua.
"We do however recommend that people who plan to visit over this period consider purchasing tickets and booking accommodation and some of our great activities and attractions early to avoid disappointment.
"Rotorua is well placed to benefit from the tournament schedule which sees the Lions play here on June 17, followed by games in neighbouring Hamilton on June 20, Auckland on June 24 and Wellington on June 27."
