Social Development Minister Bathabile Dlamini is expected to appear before Parliament's Standing Committee on Public Accounts (Scopa) to explain how she plans to pay 17 million social grant beneficiaries from the beginning of April.
Dlamini has previously not pitched for meetings with Scopa on the matter.
It's still not clear whether the South Africa Social Security Agency (Sassa) will sign a new contract with its current service provider Cash Paymaster Services (CPS).
CPS said it reached an agreement with Sassa but the contract has not been signed.
Scopa chairperson, Themba Godi, has criticised Dlamini for deliberately delaying the process.
And, Treasury says the department needs to approach the Constitutional Court if it signs a new contract with CPS as the court declared the existing contract invalid and unconstitutional.
