"He always would take his shirt off his back to give it to others."
The father-of-four had recently finished shearing for the season.
His death notice stated he was the "beloved son" of Gwen, and the late Terrance, and was loved by his many brothers and sisters.
He had also been a loving father to his four children - Jodahcei, Gemahnai, Ivorhee, and Veronika .
When asked how his children were coping, Mr Anderson said: "If you can imagine your dad dying without knowing what happened, that's what they feel like."
Finding out how Mr Sammons died would give his family some closure, Mr Anderson said.
"We don't know what's happened. We... don't know if it was hit and run, and we don't want to jump to conclusions.
"If anyone knows anything, please don't be shy. If they know anything about it please speak up, but don't speak about rumours, it has to be facts, we don't want to be creating animosity."
After seeing the body on Black St on Sunday, Mr Anderson had appealed on social media for anyone with information to come forward - at the time he did not realise it was his cousin.
"When I saw the body on the street I didn't know who it was so I put a status up [saying] 'it's a very sad day in Wairoa today, someone has passed away some brother, some nephew, if anyone knows anything can they hand themselves in', that's what I put up."
When he realised who it was, "it was [hard], I was broken".
Mr Sammons' body lay in state at Tawhiti a Maru marae in Wairoa this week. As he used to help with tangis by providing kai, members of the Wairoa community had banded together to support his family.
Mr Anderson said he would "like to thank the Mongrel Mob in Wairoa ... and all his pig-hunting friends who supported Nigel with food, koha, petrol, and for all their support.
"That's what they have done for him because he did a lot for them."
Wairoa mayor Craig Little said he did not know Mr Sammons' family personally, but paid his condolences to them.
"All I hope is everyone's patient and let the police get on with their work so they can find out what happened," he said. "It has shocked the town a bit, that's for sure."
Mr Sammons' body was taken back to Te Puke yesterday. His funeral would be held at Ngati Moko marae on Saturday, at 11am.
