$50k raised after pregnant wife and son killed in tractor accident

A fundraising page set up to help the widowed man whose pregnant wife and three-year-old son were killed in a tractor accident on the weekend has raised more than $50,000. 

Nadine Tomlinson, 33, was driving a tractor and trailer unit on their farm near Dunback in north Otago when it lost control, slipping into a reservoir on Sunday afternoon.

Ms Tomlinson's mother revealed on Wednesday her daughter was 16 weeks pregnant. Her son, Angus Tomlinson, also died in the accident. 

A Givealittle page has been set up by friends of the family to help cover funeral costs and anything else husband Scott and his one-year-old son Sam need. 

"The grief and sorrow of the loss of two children and your wife in a moment is incomprehensible for most of us," the page reads. 

"As friends of Scott and Nadine, we wish we could do more to ease Scott's pain. Fly high with the angels Nadine, Angus and wee Babe. You are so loved and dearly missed."

Mr Tomlinson said he's only just starting to come to terms with what he lost in the tragedy.

"It's been really tough. We have two boys and another on the way - I have now lost three people," he told NZME.

On Monday, the local mayor told Newshub the community was rocked by the deaths.

"It's an absolutely tragedy - the community is absolutely gutted. I'm really feeling for the family involved," Waitaki Mayor Gary Kircher says.

Federated Farmers president Katie Milne called the accident a "heart-wrenching tragedy". She said it was an "extremely uncommon" incident.
