She approached tournament director Vicki Semple, who loved the idea.
"Every year, there's an increase in athletes but that's matched by the generosity of Tauranga residents opening their doors and homes," Semple said.
"Maureen's passion and drive for this project has been absolutely incredible and it's definitely opened up options for us in future."
Maureen had secured nearly 40 beds for the visiting athletes, with plenty of ideas for more.
"I'm really proud of them here," she said of her fellow residents.
"The reaction that I've had has just been amazing and management here have been totally supportive. It's a two-pronged thing - I want to demonstrate we can all work together and it will be really good for the residents to have some company and outside interest for the week.
"My idea was to get into all the Metlife Care Villages this year. Luckily there are some moments of clarity and I realised I'd taken on a lot just organising Greenwood Park but next year, look out."
St Bernard's is a Catholic boys' school in Lower Hutt, catering for Year 7-13 students. This will be the school's first trip to the AIMS Games and director of sport Andrew Cavill said the Greenwood Park offer had been an ideal solution.
"Finding accommodation in Tauranga was a real issue but staying at a lifestyle village will be new and exciting for the boys," he said.
"It will be good for them to be able to stay with an older generation and hopefully the residents will really enjoy having our boys there as company too and will get in behind them."
Cross country and rugby sevens are held at Welcome Bay's Waipuna Park, just down the road from Greenwood Park, which was how sports-loving Maureen - who still plays bowls three times a week - came to love the tournament.
"I used to go all the time with my late husband Des and watch the cross country on the opening day. I've always read the papers and kept an interest in things but this tournament is part of Tauranga. It's been going for so long and it's so great for the competitors to experience something like this."
Besides, it gives the super-fit septuagenarian something else to get her teeth into. Earlier this year, she helped Greenwood Park collect and distribute several trailer-loads of necessities for flood-struck Edgecumbe residents.
"I've always believed that you always contribute more into the world, than you ever expect to take out of it," she said.
The 2017 Anchor AIMS Games will run from September 10-15 at a range of venues across the Western Bay of Plenty. The premier sporting event for 11, 12 and 13-year-olds is a strategic partnership between Sport Bay of Plenty, Tauranga City Council and the four Bay of Plenty intermediate schools.
It involves 10,139 athletes, 302 schools and 21 sports.
