The Chiefs outside back trio of Tim Nanai-Williams, Robbie Robinson and Asaeli Tikoirotuma have all re-signed with the franchise until 2014.
"These are all quality players, who have bright futures and are an important part of the Chiefs programme," Chiefs coach Dave Rennie said.
Robbie Robinson said the move up north from the Highlanders had paid off.
"I had some personal goals that I wanted to achieve and feel I am heading in the right direction and improving in the Chiefs environment."
Joining Robinson in re-committing to the side is Counties Manukau's Tim Nanai-Williams.
Williams is in his third season with the Chiefs and is rapt to stay under the guidance of the Chiefs coaching team.
"The Chiefs are one big family and family and loyalty are important to me," the 23-year-old Williams said.
Asaeli Tikoirotuma has also been impressive in his debut year, which included scoring four tries in one match against the Blues.
Tikoirotuma commented on his new contract "I love being part of the Chiefs. Super Rugby is just awesome and I'm really enjoying it."
The Chiefs meet the Crusaders in Hamilton on Friday with a spot in this year's Super Rugby grand final on the line.
