The group, led by provincial president, Greg Harris, includes the Rural Support Trust, Ministry for Primary Industries, Beef & Lamb, Dairy NZ and the Marlborough District Council.
The Onamalutu Valley - Northbank fire last week has already burnt around 620ha, including forest, tree lots, some agricultural land and small holdings, with a large number of rural residents affected.
While the fire is largely under control, helicopters and ground crews are still monitoring the situation, and continue to work within the fire area.
Federated Farmers and the Rural Support Trust are providing support to those farmers affected.
