Scott Gregory will line up at second-five as New Zealand look to emerge from pool play at the World Rugby U20 Championship in France.
They take on Australia, who need victory to have any chance of progressing further in the tournament.
Hikurangi's Gregory is one of a raft of changes from the team that eased past Wales 42-10 despite discipline issues.
The game kicks off tomorrow morning at 7am.
