The Silver Ferns will sharpen up for this weekend's opening test against Australia with a couple of rare hit-outs against African nations.
South Africa and Malawi will play the curtain-raiser to Sunday's opening Constellation Cup match as part of a sporting festival in Perth to coincide with the Commonwealth Heads of Government Meeting (CHOGM).
While they are over in this part of the world they will also get exposure to top-level competition, with warm-up games against New Zealand, Australia and the Australian Under-21 side.
Silver Ferns shooter Cathrine Latu said the two sides would provide an ideal lead-in to the Australian series.
The Ferns will take on the world No 6-ranked Malawi side today, before meeting South Africa, who gave New Zealand an early shake-up in their world championship quarter-final match-up, tomorrow.
