Mr English told Larry Williams the re-shuffle will be "narrowly-focused".
He said the main priority is having a Cabinet that delivers for the public, not trying to work out what their new roles entail.
"We will be replacing the two Ministers who are leaving who have done great jobs - Hekia Parata and Murray McCully - and fortunately we have a large pool of talented and skilled and motivated people to take those slots."
Nikki Kaye is almost certain to replace Ms Parata as education minister, while Jonathan Coleman or Gerry Brownlee are both tipped to take over as Foreign Affairs Minister.
Newstalk ZB's political editor Barry Soper said Nicky Wagner is likely to be made Health Minister.
"These are relatively short-term," he said. "Only five months to go before the election, so he won't want to be doing anything too significant today."
