A traditional chief in Zvimba district, which includes Kutama, said he had received a complaint from a Mugabe clan member over the manner of his burial.
The former first lady, who did not attend the hearing, was fined five cows and a goat.
“I give powers to those who are permitted by law to exhume the late Robert Mugabe’s remains from Kutama and rebury them at the National Heroes Acre in Harare,” said a copy of the ruling in the local Shona language.
Leo Mugabe, spokesman for the Mugabe family, immediately rejected the ruling.
“He (chief) has no jurisdiction over Kutama. And even if the correct chief had made that ruling we would have appealed to the court,” Leo Mugabe told Reuters.
Chiefs in Zimbabwe have jurisdiction over their local subjects but it is rare for them to order families to exhume bodies for reburial.
The chief’s order will likely rekindle a row over Mugabe’s final resting place.
