'Visa regulations are necessary for national security'
Mantashe says Hanekom and Gigaba have no excuse for arguing with each other in public.
Last week, Hanekom said the regulations were damaging the tourism industry, while Gigaba said they had to stay in place to stop child trafficking.
Mantashe says Hanekom and Gigaba shouldn't have given radio interviews on this subject last week and said they had no excuse for arguing with each other in public.
"They should not have raised those issues [in public]; they don't need to talk to journalists."
He says there are ways to sort out these difficulties.
"We should have meetings behind closed doors and discuss issues there; and see what it is that should be attended to."
Mantashe says while parts of the Immigration Act may change, these regulations should stay in force for now.
"The Immigration Act is a good law, it is necessary for national security, but if it impacts negatively on other areas of work it must be revisited."
