Managing director Ryan Holmes said it was exciting to have Dialled Indoor Tramp Park on board.
"It's going to be big, it's around about 1120sqm they're taking within the entertainment building. What their concept here is they will bring not only a trampoline park but also have a mountain-bike theme, big ramps where you can do big flips into sponge pits and practise your moves before you hit the mountain, so to speak."
Dialled designer and managing director Kell Travers said the company's arenas were designed and constructed in Mt Maunganui and were built by Kiwis for Kiwis.
"In addition to our amazing trampoline area, we are excited to announce the addition of a large raised Ninja Warrior obstacle course consisting of hanging obstacles, flat lines, monkey bars, tarzan and trapeze swings, raised platforms and parallel walls, plus much more. The area will blow the minds of our customers," Mr Travers said.
"We're also working on an area to suit mountain and jump bikes, including a 10 foot-high (3-metre) roll into a huge bike foam pit. If space permits, we may have an indoor mountain-bike course, a first in New Zealand. Because Rotorua is New Zealand's's mountain-bike capital and I love riding there, I really want to incorporate somewhere indoor to ride that suits families travelling to Rotorua."
Mr Travers said the company felt there was a lack of quality indoor entertainment in the city.
"So we are very excited to be part of New Zealand's largest indoor-entertainment facility in Lynmore Junction. The entire concept will be sensational and we're looking forward to being involved with the Holmes Group along with some of New Zealand's best indoor entertainment operators."
Mr Holmes said he expected there to be employment opportunities for Rotorua and was working on filling the last space with a tenant at the junction.
"It will create jobs. It's a new concept and new brand to Rotorua so it will create jobs as will the overall centre.
"It adds another component to the overall concept and our vision to have an all-weather tourist attraction and not just go there in an isolated area and spend 15 minutes jumping on a trampoline. They can come here and have a whole integrated experience and the whole family can come along - grandparents, uncles, aunties, they can have birthday parities there, family reunions, team building as well."
The centre is set to open in September next year.
