Cde Muntanga died at Falls Medical Centre in Victoria Falls on Sunday morning after a long struggle with a heart problem.
Cde Muntanga was the first Member of Parliament for Binga, serving the constituency for three consecutive terms.
Acting Zanu PF Chairman for Matebeleland North Province, Cde Zwelitsha Masuku, said Cde Muntanga started political activism in the late 1960s while working for Lever Brothers.
He said Cde Muntanga was introduced into politics by the likes of the late Father Zimbabwe, Dr. Joshua Mqabuko Nkomo and Cde Joseph Msika.
Cde Muntanga was involved in mobilising support for freedom fighters in Hwange, Binga, Bulawayo and Gokwe during the war of liberation.
A family spokesperson, Ms Virginia Muntanga, described the death of Cde Muntanga as a great loss to her family and the people of Binga at large.
“He was the source of strength, inspiration, love and unity of our family,” said Ms Muntanga.
According to Cde Enoch Sibanda, former Zanu-PF Central Committee member, Cde Muntanga was instrumental in the fight against colonial rule in Binga.
“During the struggle, he was in charge of logistics. I remember him sending some trucks to Chimoio, Mozambique, with food for our comrades,” he said.
Cde Sibanda said Cde Muntanga became the deputy organising secretary for Zapu after independence.
In 1963, Cde Muntanga joined Zapu and in 1966, Cde Muntanga was declared a prohibited immigrant in Binga for an indefinite period. He spent a year in detention for political reasons.
In 1975, he became a Central Committee member, the first among the Tonga people.
He leaves behind his wife Regina and 6 children.
Mourners are gathered at house number 2594, Chinotimba, Victoria Falls.
