Home Affairs Minister Aaron Motsoaledi said that people crossing borders into South Africa must have COVID-19 clearance certificates.
Motsoaledi is visiting the Lebombo Border Post as the country reopened 20 land borders today.
Cabinet decided to reopen travel to neighbouring countries after borders were closed early January in an effort to control the spread of coronavirus.
Motsaoledi has dispatched senior staff officials to the busiest ports of entry to monitor the implementation of their border control plan.
He said the management of people, through borders, remained an important part of a strategy to control the spread of COVID-19.
He said that any person who wants to be in South Africa will have to produce a certificate and that they think they have made life much better because those certificates are not cheap .
