But he is free to play at club level and is set to make a return to the field in September.
"We're delighted to have him. He's one of the best players Australia has had since World War II," he told the local Southern Courier newspaper on Wednesday.
"He's been speaking to one of our club officials and he has committed to the first three or four rounds of the season. Why it is only three or four rounds at this stage I don't know."
Warner has also been linked with playing in the Northern Territory's limited-overs Strike League.
Whitney, who played 12 Tests for Australia, said he emailed Warner shortly after he was banned in April to tell him the door was open.
"Everyone is excited to have him. He will be great in the changing rooms with younger players," Whitney said.
He was identified as the mastermind behind the plan to tamper with the ball. While former skipper Steve Smith was charged with knowledge of the plot, Warner was charged with developing it and instructing Cameron Bancroft to carry it out.
