President Cyril Ramaphosa has extended the deployment of soldiers.
The extended deployment of South African National Defence Force (SANDF) 20,000 members is expected to cost R1.5-billion.
The soldiers were deployed at the beginning of the lockdown to help maintain law and order.
Ramaphosa first deployed 2,820 members but the number was increased to 76,000 in April as the health threat grew.
Ramaphosa has informed Parliament on Thursday of his decision to extend the deployment of 20,000 soldiers, a drop from 76,000 until 30 September to help enforce COVID-19 restrictions as South Africa recorded its biggest single-day jump in coronavirus cases.
South Africa started slowly reopening parts of the economy from May and again in June but infections have started to spike again.
On Thursday, South Africa reported its biggest single-day jump in coronavirus cases, adding 8,728 confirmed infections and taking the total count to 168,061, according to health ministry data. Deaths rose by 95 to 2,844.
In related news, about 40 South African National Defence Force members have been infected with COVID-19.
The battalion was deployed from Cape Town to Limpopo, to patrol the border with Zimbabwe. The soldiers were quarantined both before leaving Cape Town and on arrival in Limpopo.
Despite this, several members showed symptoms and the entire battalion was tested. The infected soldiers will remain quarantined until they recover.
The matter was reported to national Health Minister Dr. Zweli Mkhize and the head of military health services.
Soldiers from different units have been deployed all over South Africa and the composition of its members is not from one region.
