The 15 were admitted to Mutoko District hospital.
Mutoko was the hotbed of violence, in the run up to the disputed March elections last year.
Ordo Nyakudanga, the Member of Parliament for Mutoko East, confirmed the fresh incidents of political violence at Mushimbo business centre, 10 km from Mutoko centre.
"We are meeting all the political leaders to educate people about the inclusive government. I appeal to the people of Mutoko and Zimbabwe at large to let by-gones be by-gones and emulate their leaders who have embraced reconciliation and peace for the sake of development in Zimbabwe," Nyakudanga said.
The victims reportedly sustained injuries of various magnitudes ranging from deep axe cuts to internal injuries.
Relatives of those who were implicated in the attacks and were detained at Mutoko police station for grabbing livestock such as chickens, pigs, goats and cattle, were convinced the attacks were a pay back for inter-party clashes that were perpetrated during the election time last year.
