The shortest member of the team is only 1.5m and the tallest 1.625m. They play against New Zealand teams with players ranging from 1.8m to 2m.
The Guam team lost its first game yesterday to Tutu's on Tour 47-43.
''We fell short by four points,'' Tina Rose Muna Barnes said.
''Not bad considering the size of the women we were competing against.
''We are a very small and short people.
''Being able to catch a rebound is almost a miracle for us.''
The eight-strong team ranges in ages from 32 to 52 with senator Barnes from the Guam Legislature the oldest.
The team also includes a lawyer, a professor of criminal justice, three military personnel, two teachers and an artist.
The best players in the Guam team are Hariet Alvarez, Cil Olandez and Rei Constantina, who is an outside shooter and likes getting three-pointers.
Guam has sent a basketball team to an overseas Masters Games every year for the past five years.
''It helps promote the island of Guam to other countries in the Pacific region and helps team members to collaborate and have camaraderie with people from different countries,'' Barnes said.
Guam was the host country for the South Pacific Games in 1999 and will host the Festival of Arts in 2016.
''It will be the 12th Festival of the Arts in this region and I would like to invite the people of New Zealand to join us,'' Barnes said.
Basketball is a popular game in Guam and it is played in all schools.
''We play a lot of American sports so basketball, baseball and football are important ,'' the senator said.
The country is also being helped by the International Olympic Committee to develop its Olympic Games sports.
Guam accepted an invitation from New Zealand to compete in Dunedin when it competed in the Pan Pac Masters Games in Australia.
It is the first time that Guam has sent a team to compete in New Zealand.
''It took us a long time to get here but it's been worth the journey,'' Barnes said.
''There are limited opportunities for masters women to play basketball back home,'' she said.
She is also president of the Guam Women's Basketball Association. ''It was formed to promote health and wellness and also to promote women's sport,'' she said.
Barnes, one of 15 elected members of the senate legislature, has been a senator for 32 years. Guam has a population of 168,000 and there is a groundswell of support for Guam, a territory of the United States, to have more autonomy over its governance.
The team has enjoyed its stay in Dunedin and attended the Ngai Tahu Treaty Festival at the Otakou marae, part of the Waitangi Day celebrations, and visited Tunnel Beach and St Clair.
''Dunedin is a beautiful city and we are enjoying every minute of our visit,'' Barnes said.
''But it is very cold for us. We have very humid temperatures back home.''
