''He was a big man - a massive guy - he was a real gentle giant, but a very soft, kind man. He was generous and would do what he could to help others. He loved kids and he's even taken in other kids to look after,'' Pitt said.
''If anybody moved over there he'd help them find a job and place to live.''
She said Tana was one of 13 cousins who grew up together and treated each other as brothers and sisters, and his loss was being felt hard among the whanau and those who knew him.
''He was such a dedicated family man, father and loving husband to Melissa and the kids and a great friend and work colleague to many. We know there are many who would like to help Melissa and the kids to bring Shannon home to Ngunguru where he will be laid to rest,'' Pitt said
Tana had recently been involved in planning an event for the Goldfields Children's Charity, which would still go ahead in November.
Police are seeking witnesses to the crash, as well as any dash cam or CCTV footage to assist with investigations.
