The Proteas could send a weakened squad to New Zealand for their two-Test series against the Black Caps in February.
The first Test will get underway on 4 February at Bay Oval in Mount Maunganui, Tauranga, with the second to start on 13 February at Seddon Park in Hamilton.
The Proteas will also play a three-day warm-up match from 29-31 January in Christchurch.
The tour will clash with the second edition of the SA20 league, which is set to start in the second week of January.
“The SA20 for us is non-negotiable,” CSA CEO Pholetsi Moseki told TimesLive. “However we also understand the obligations we have in terms of the FTP [ICC’s Future Tours Programme].
“We know there will be a clash, but only once we know how many of the contracted players will be picked up in the [SA20] auction will we be able to get a clearer picture of what the [Proteas] squad could look like.”
The Proteas last toured New Zealand in 2022, sharing the Test series 1-1.
