The receivers for the Crafar dairy group are taking legal action to force the Crafar family off their farms.
The Waikato family's central North Island farm holdings went into receivership in October last year, owing more than $200 million to lenders.
The Crafars have refused to leave their dairy farm at Reporoa despite a relocation offer which expired almost two weeks ago.
Receivers KordaMentha had offered Allan Crafar six months' free rent in Rotorua if his family would leave the farm by 8 April.
KordaMentha say they are now pursuing legal processes to gain possession of properties where the Crafars are living.
One of the receivers, Brendan Gibson, says the Crafars have refused to move despite a trespass order issued against them.
The receivers says the receivership is one of the most intense they have encountered and they have had to pour in money to remedy the dire condition of the farms and many of the animals.
Radio New Zealand News has not been able to reach the Crafer family for comment on Wednesday.
