Police said the exact circumstances are still to be determined. An investigation has been opened by WorkSafe and the death has been referred to the coroner.
"Police pass on our deepest sympathies to his family and friends."
It's the second farm death in Hawke's Bay in as many weeks and the fourth across New Zealand in the past month.
Two involved tractors in Te Kuiti and Hastings, and another involved a child in a dairy shed in Opotiki.
On September 17, one person was killed near Maraekakaho when a tractor likely slipped on steep terrain while feeding out.
Police have yet to officially release the name of the person killed and WorkSafe is still investigating the incident.
Hawke's Bay Federated Farmers president Jim Galloway said both the fatalities in the region were tough on families, friends and the farming community.
"We are just so sad at the tragic loss this family and all involved are suffering.
"It has been a long hard year, not only have we had a terrible drought to contend with, but a global pandemic, and some tough legislation.
"These accidents add more stress and pain on rural communities.
"Everyone needs to be aware of the conditions and terrain where they are working and that they change, sometimes rapidly.
"The incident occurred on steep terrain, but we will not know more until Worksafe have completed their investigation.''
WorkSafe agriculture engagement lead Al McCone said farms' slope surfaces are especially tricky at this time of year.
"It is a time of variable weather and growth, and variable ground surface conditions," he said.
"There is also a shortage of contractors and some farmers will be doing tractor work that normally a contractor might do with equipment better suited to the task.
"We cannot let these challenges contribute to loss of life or injury."
McCone also said seatbelts should always be worn when doing farm work.
"Mistakes happen and your seatbelt might be the difference between a sore neck and a broken one," he added.
