She needs $5000 to get there and friends and family are now asking members of the public to come forward to help her achieve that dream.
A fundraising event (a dinner and auction) is being held at the Havelock North Community Centre at 6.30pm on Friday, August 3.
Tickets cost $55 and those attending are encouraged to donate a luxury item for a raffle.
Owner of fundraising works Bronwyn Harman says one of the All Blacks has even come on board to support Barr's ambition.
"Brodie Retallick (who knows Laura) has managed to get an all black shirt signed by the team plus we have a unique auction item for a group of kids to be picked up by a fire engine, taken to the Havelock North Fire Station and being allowed to play with the hoses etc ( all supervised by real firemen of course) - plus many other things."
Now 27, and four years on from her husbands death, Laura says she's still taking things "one step at a time".
"It's okay to have those days where you just don't want to get out of bed, but remember that you're still here and whoever you've lost, they wouldn't want you to go downhill, they would want you to keep going for them."
Laura says Outward Bound has always been one of her strong ambitions and feels it would be a huge confident boost for both herself and four-year-old daughter Asha Rose.
"I always thought about doing it in high school-but it never really came to anything.
"I think it would be good to prove to myself that I can do something that is going to be quite challenging both emotionally and physically. I feel quite ready to prove to myself that I can do this to show Asha that whatever challenges do come-you can get through it."
Laura says although she was looking forward to the challenge, it was going to be an emotional challenge being away from her daughter.
"There's no phones or internet, so for me that's going to be a huge challenge because we're so close.
"We both rely on each other and bounce off each other, so to be away from her is going to be really hard."
Laura feels incredibly lucky to have such supportive friends and family, as she hadn't considered a fundraising event to get herself to Outward Bound.
"This kind of event helps bring people together as well and I'm just lucky for the love and support I do have.
"After all this support I want to prove that I can do something like Outward Bound, not only for myself, but for those who are rallying to help me get there."
