"I feel very excited and proud of myself for both these things," says the 28-year-old, who has been drumming and dancing since he was a child.
Armstrong, who served for five years on the Wellington City Council's Youth Council, says he is proof that you shouldn't judge people before getting to know them. Born with trisomy 21 (Down syndrome), he recalls how he and his family had to battle to convince teachers that he could attend school.
"I sometimes feel excluded and that makes me very angry," he says. "I have friends who stick up for me and, when people get to know me, they find out how capable I am but they have to give me the opportunity first."
Bell, an internationally recognised contemporary dancer, was paralysed from the chest down in a motorcycle accident in 1991. After rehabilitation, he joined the New Zealand wheelchair basketball team before becoming a founding member of Touch Compass.
He says people are becoming more open-minded and accepting of the contribution differently abled people make to the arts as participants and consumers.
"I hope, looking to the future, this inspires other people who do things differently," says Bell. "This award is made possible because of a lot of people in my life."
He also knows about the impact poverty and homelessness can have on access to the arts. In 2012, after five years as one of the principals at the AXIS Dance Company, Bell found himself living on the streets of San Francisco when his contract ended. He lived on the streets for three years before returning to New Zealand in 2015.
He has since crafted the dance work Meremere, with choreographer Malia Johnston, which draws on his disability, his Maori heritage, life on the streets and passion for movement and connection.
While Bell plans to tour this nationally and internationally, including to prison, marae and schools; Armstrong would like to make another film.
Richard Benge, executive director of Arts Access Aotearoa, says one in four people in New Zealand - more than one million - live with a disability or impairment.
"That's a lot of people, who all have the right to enjoy the arts as artists, participants, audience members and gallery visitors."
