The Ireland Under-19 squad to face Australia Schools at Ravenhill on Saturday week (December 14) has been announced.
Heinke's wife Nicole is due to give birth within the next two weeks, so as soon as their child arrives, they will make the move to Ireland.
van der Merwe said that he is very excited for the move, explaining: "We will have a baby and are leaving our home and our country for two years, so amidst all the nerves and tension, we are both very excited.
"This is an opportunity that has come up, that I certainly couldn't say no to it."
Leinster will be announcing their playing squad and coaching team for the 2010/11 season in the next fortnight.
