Bundee Aki has edged closer to Test rugby with Ireland by rejecting a move to France to sign a new Connacht deal until 2020.
Ireland's promising lock Ultan Dillane has also completed a two-year contract extension to remain at Connacht, in a double boost to boss Pat Lam.
Auckland-born powerhouse Aki is understood to have rejected moves to Bordeaux and Munster and will now qualify for Ireland on residency next year.
Reports in the Irish media suggest Dillane was also of interest to Munster, but two of Connacht's key stars have instead opted to remain with the reigning Guinness PRO12 champions.
"I'm really pleased that Bundee and Ultan have committed their futures to Connacht Rugby," said Lam, admitting both stars had fielded offers to move elsewhere.
"Two talented rugby players, naturally their performances have attracted a lot of attention - and there is no doubt that they had options in terms of where they could play.
"But I believe it is a massive statement about what we are doing here as a team and an organisation that they were both so determined to continue to play their part."
Aki, the former Chiefs centre, has lit up Connacht's back division with his powerful line-breaking instincts since his 2014 arrival.
The 26-year-old will add a bullish midfield edge to Ireland's Test options once available next year after completing the three-year residency period.
Dillane, the home-grown 22-year-old second-row, already boasts six Ireland caps after bursting onto the senior scene in the last 18 months.
