The visa-waiver agreement with South Africa is to be reviewed amid suggestions that terrorists and criminals are travelling on fraudulently obtained passports from the republic.
A Cabinet paper recommends Immigration Minister Nathan Guy and Associate Minister Kate Wilkinson review the arrangement by the end of the year.
"There are concerns about the fraudulent use of South African passports by non-South African nationals and the availability of fraudulently issued legitimate South African passports," Mr Guy said.
"While Immigration New Zealand has been very successful in managing these risks to date, it is appropriate to reassess the current visa-waiver arrangement ... to determine whether a change is warranted."
In the 12 months to February, 72 people have been prevented from travelling to or entering New Zealand with what were thought to be fraudulently obtained South African passports.
