Joseph Parker's hometown, south Auckland, prepares for Anthony Joshua fight

As boxer Joseph Parker gets ready for the fight of his life, so too are his supporters in his community in south Auckland.

His fight against Anthony Joshua in Wales on Sunday morning leaves many fans torn between whether they go to church or watch the fight.

The community is still excited despite the clash, with Māngere locals fighting fit as their boy prepares for the fight of his life.

"He's going to win, positive," one person says.

In Wales his opponent had a lot more support at the weigh-in, but at the markets in south Auckland it's Parker all the way.

"I can't wait for that fight," one person says.

"I think this is the right moment," another says.

From humble beginnings Parker's rise is extraordinary. People here are extremely proud one of their own has made it to the top.

"It's going to mean a lot to the Pacific Island people, the Samoan people, the New Zealand people, to all New Zealanders," one person says.

"All the greats are from here - Jonah Lomu and the All Blacks. It's just going to be awesome, aye," another says.

Another of those greats, David Tua, is also showing his support.

"I think he's ready. He's done his work. I think the rest is up to him."

Like Parker, many of his supporters are religious and will be attending church rather than watching the fight. Some ministers Newshub have spoken to say they'll pre-record the fight, as they will be in church and they'll be offering special prayers for Parker.

"He's the Lord's man. He respects the Lord, so we'll balance it up, just this once," one person says.

Many who are watching the fight live will gather in lounges across south Auckland.

"At mother-in-law's place we'll have drinks and chop suey, and yeah we'll be getting into it," one person says.

Whichever way it goes on Sunday, Parker's already a winner at home.
