"We are really grateful to Real Rotorua. We really appreciate, once again, when local businesses put on events for us."
Darryl says they are in need of male mentors, as the programme currently has a number of referrals for boys but they did not have any male mentors available.
He says the mentors enjoy the programme as much as the children.
"They make a close bond and friendship, and find that rewarding."
He thinks for the men it's quite low key and fun, based around a lot of activities the boys do not get to do.
Mentor Ross Fowler says he has been involved in the programme for nearly two years.
He says he joined because he wanted to make a difference and make someone's life a bit better if he could.
Ross says he gets as much out of it as his 'little brother' Phoenix, 11.
"It's rewarding. You build up a great bond and he feels comfortable talking about everyday stuff he's not always comfortable talking to mum about."
Ross says it may allow the boys to do things they would not do otherwise, as their mother may not have the resources or time.
Ross says his own mother was a solo mother herself.
"This is supposed to be for a lifetime, which I think is fabulous and it's certainly my goal."
Mentor Eldon Lomas says he has been involved in the programme since January.
His 'little brother' Josh, 12, lives with his grandparents who are in their mid-70s.
He says he saw an article in the paper about the programme and thought it would be an amazing opportunity.
He had an experience with cancer and because he was recovering he had the time to do the programme - "It's just nice to be able to do something to help a kid out".
Eldon says he has been pretty lucky as far as his family goes but some children come from quite difficult family backgrounds.
He says he would definitely encourage others to get involved because it is rewarding and makes a difference in people's lives.
They say other group outings through the programme have included going to Skyline, a magic show and Lake Rotoiti. There are also mentor get-togethers.
Mr Julian says the trip was two and a half hours on a nocturnal expedition in native New Zealand forest.
He says he had talked to a customer about Big Brothers Big Sisters and decided to take them out as lots of people have not done things like this, especially at night.
Before the expedition, Taylor, 10, and Luke, 13, said they were looking forward to hanging out with mates, making new friends and seeing new things such as wallabies.
Some of their favourite activities to do with their 'big brothers' are swimming and mountain biking.
