Ben Tameifuna
Tameifuna, a strong scrummager with the ability to score tries from close range, said the decision to stay was an easy one to make due to the support he received.
Chiefs coach Dave Rennie said the 22-year-old has made big shifts on and off the field.
"We are really happy with Tama. He's a powerful man, a destructive tackler with an impressive skillset."
