Otu volunteers at Wesley Community Action, an organisation that runs social programmes to help the community, including a food bank and budgeting services. She also volunteers at Mary Potter Hospice, after the death of her 21-year-old son from cancer nearly eight years ago. And she helps out at the local playcentre.
But what Otu really wants is a job, to help her family climb out of the cycle of poverty. It's a cycle which, at times,made it hard to feed her children-all adults now but mostly still living in Cannons Creek, beneath the shadow of the new privately-built Aotea subdivision.
The cheapest Aotea house currently listed on TradeMe is a four-bedroom, two-bathroom property for $519,000;most are considerably more-one sold this week for $845,000. Some have views of Porirua Harbour, Titahi Bay and the Tasman Sea. Others look out over the top of Champion St, the multicultural Cannons Creek melting pot made famous by children's author Patricia Grace, to Wellington's Belmont Trig.
Down in Cannons Creek, you can pick up a three-bedroom, one bathroom property for $175,000.
But top Harcourts real estate agent Marty Ritchie,who sold the $845,000 Aotea house and lives in the new subdivision, plays down the inequality between the two neighbourhoods.
"When I started out, Cannons Creek was like Once were Warriors. There were burned-out cars on the front lawns," he says.
"But if you meet the people who live in Cannons Creek, they're very, very happy people. To them it's just another development.
"We've sold houses in Aotea to families from Cannons Creek.
It's the families who want to get ahead, who pool resources to buy a modern house. If you look at the people who are living in Aotea, we've got all cultures. I don't think there's an issue."
Otu Ahiao doesn't begrudge those in Aotea their wealth. Nor does she aspire to live there, happy withwhat she says is a fantastic sense of community in The Creek.
"They're there and we're here but tome, we're the same," Otu says. "It's just that they're in a different category, that's all."
"I've taught my children, let's be grateful for what we've got. And if you can help somebody out, then help them."
