Are there NZ or Australian natinal teams protagnist who play in URC?

If I remember well, until 2019 there were many southern hemisphere famous players - we can cite Sonny Bill Williams, François Steyn and others- playing for english or french clubs or even in Italy and Ireland, but they usually come north after 30 years old, of course very fot and motivated, but they did not retain their place in their national teams.

I wonder if there are, besides the Sprongboks that play all for SA franchises, austrans or new zealanders that are both nationals and playing in URC
