Looking to build on the stunning form which saw them top the New Zealand conference, the Waikato-based franchise expressed the importance of securing the trio, who have been among the club's best this season.
"These are all quality players, who have bright futures and are an important part of the Chiefs programme," said Chiefs coach Dave Rennie.
A former star of Highlanders rugby, fullback Robbie Robinson said that the decision to move North had definitely 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," said Robinson.
Another electrifying prospect, Counties Manukau winger Tim Nanai Williams said the Chiefs had become more than just a rugby club to him, making it an easy decision to stay on.
"The Chiefs are one big family and family and loyalty are important to me," said 23-year-old Williams.
The contract extension will see Williams play a total of five seasons with the Chiefs.
Asaeli Tikoirotuma has also been impressive in his Super Rugby debut year, equaling a previous record - held by Sitiveni Sivivatu - of scoring four tries in one match, against the Blues.
Reflecting on his decision to re-sign Tikoirotuma said: "I love being part of the Chiefs. Super Rugby is just awesome and I'm really enjoying it."
