But as they crossed the swollen Mahurangi River, north of Auckland, they were swept into the water.

Local police and specialists from Search and Rescue scoured the water and banks of the river for Arobati but it was his brother-in-law Kai Tenanoa who found his body.
“Tekanimaeu is my best friend, I call him my brother,” he told RNZ.
“I fight for the goal to find him, and the success, we thank God he brought him back to us.”
The pair went to school together in Kiribati, with the woman who Arobati would eventually marry.
Tenanoa said the community had rallied around the family.
“I think they are very lovely people,” Tenanoa said.
“We didn’t ask them ‘come and join us’, they all came straight to the wife, and said we want to come with you,” he said.

It was Tenanoa and others who found Arobati in the river.
“I thank God, and I thank all the Kiribati communities in Rodney for their support to find him.
“We thank police for everything, for the searching, but now we succeed because of God, of love.”
Search crews had scoured the area from Falls Rd in Warkworth along the river for any sign of Arobati.
He was found roughly 200m from the crossing where he disappeared.
His car is yet to be found.

His wife, Tirutinia, was thankful for all the help her family had received.
“I would like to give my special thanks to my community, because they were the first one to see my husband, and they were the ones … [to] call to the policemen … they found him after three days,” she said.
“I should thank my brother-in-law, my sister’s husband is the one that first saw my husband, with my firstborn son and other boys.
“I’m really thankful for all the Kiribati community because they all came that time, and they did their best.
“I know it’s a risky place to walk along, but they still took their steps to look for my husband, and fortunately, they found him at last.”
She said the Kiribati community had helped her get back on her feet.
“They’re very supportive,” she said.
“They came, and they told me ‘You’ll be a single wife, but remember that your husband is still there’.”
Arobati’s death has been referred to the coroner.
A Givealittle page has been set up to support the Arobati family, with more than $3000 raised so far.
