The two were arrested on Saturday following a tip off that there was a car transporting rhino horns.
It is one of the biggest hauls of rhino horns in the country, according to an elite police unit that investigates specialised types of crime known as the Hawks.
"It was an intelligence-driven operation that led to the arrest of the two. They were found in possession of those 167 rhino horns," he said, adding "it is one of biggest (hauls)".
Police said the rhino horns worth a "substantial amount of money" were destined for the Southeast Asian markets.
In reality rhino horn is a nostrum, comprised of little more than keratin, the same protein that makes human hair and fingernails.
Nonetheless horn can fetch up to USD 60,000 per kilogramme in Asia, stoking lucrative transnational crime networks that have decimated rhino populations in recent decades.
South Africa, which is home to about 80 per cent of the world rhino population, has been hit hardest.
In 2018, 769 rhinos were poached in South Africa alone. More than 7,100 animals have been killed over the past decade.
