Nyauza was one of three players withdrawn from Bafana Bafana this week, including Bucs teammate Thabo Matlaba and AmaZulu left-back Marc Van Heerden.
Pirates are currently in the middle of their CAF Confederations Cup campaign, with the domestic season also looming on the horizon, therefore the 25-year-old had to relinquish his spot in current squad.
However, 'Ntsiki' is confident that his withdrawal will not threaten his place under coach Shakes Mashaba for future Bafana duty.
