Moerat is one of several players to come into the starting line-up for the North-South encounter at Loftus Versfeld, which kicks off at 19h00 on Friday, and will be refereed by AJ Jacobs.
In the backline, Damian Willemse is at fullback and will link up with wings Leolin Zas and Edwill van der Merwe, while Rikus Pretorius comes into the midfield and Paul de Wet makes a start at scrumhalf.
In the pack, Moerat will partner David Meihuizen in the second row and there is an all-new front row of Leon Lyons, Chad Solomon and Sazi Sandi.
There is also significant experience on the replacements bench, with the likes of JD Schickerling, Herschel Jantjies and Tim Swiel all getting their first run in the preparation matches.
DHL Stormers coach Labeeb Levy said that the team is looking forward to the challenge that awaits them.
“It has been a good week of preparation so far and we are focused on showing what we have worked on when we take the field on Friday," said Levy.
“We have some talented players coming into the mix this week, along with some players that have really taken their opportunities in the previous two games, so we want to find some fluency as a unit."
