The 28-year-old's current deal at the Falcons was due to expire in the summer, with Gopperth's form earning him the attentions of a number of sides.
And with Newcastle in danger of being relegated from the top-flight, it appeared the club faced a losing battle to keep hold of their star man.
However the New Zealander, who arrived at Kingston Park from the Blues from 2009, has now agreed a new three-year deal.
"My family and I are delighted to have been given the opportunity to extend my contract at the Newcastle Falcons," Gopperth said.
"I have been humbled by the offers from other clubs, however I feel that I have unfinished business here. Furthermore I very much want to be part of what I believe is going to be an amazing journey here at Newcastle.
"I have a lot of respect for club owner Semore Kurdi, he is not a man of many words but his ambition, drive and belief in this club is clear for all to see.
"I whole-heartedly believe that we have a great squad here. The team environment is second to none and I am excited to see what we as a team can produce going forward."
Gopperth's commitment follows the arrival of a new coaching team at Kingston Park - with director of rugby Gary Gold joined by Mike Ford and John Wells.
And Gold added: "I am extremely delighted that Jimmy has committed his future to the club and it is an incredibly strong sign of intent.
"I know full-well that there were a host of other clubs after his signature. He is an internationally renowned player who has made his intensions clearly known and it is a massive step forward for the club."
