Schwalger named Samoa head coach until 2027 Rugby World Cup
Schwalger, 45, was assistant to head coach Vaovasamanaia Seilala Mapusua at last year's World Cup in France, where Samoa exited the pool stages after just a single win, against Chile.
"Representing one's country, whether as a coach or player, is the pinnacle of sporting achievement, and I'm deeply humbled by this opportunity," Schwalger said in a statement Tuesday.
"I'm eagerly looking forward to the journey ahead."
Samoa will host Italy and Spain in July before taking part in the Pacific Nations Cup with Canada, USA, Fiji, Japan and Tonga in August.
Schwalger, a hooker, played 40 Tests and captained Samoa to the 2011 World Cup.
Schwalger played Super Rugby for the Otago Highlanders, Wellington Hurricanes and the Waikato Chiefs and had stints abroad at Llanelli Scarlets and Sale Sharks, before retiring in 2014.
