Gidley who began his career with the club 10 years ago has re-signed until the end of 2015 after penning a four year deal on Wednesday.
The 28-year-old Test utility will be 33 at the end of his deal making him a Knight for life joining the likes of Andrew Johns.
“Yesterday we asked our supporters to make a commitment to the club by purchasing memberships in 2011, today I’m excited to be cementing my commitment to the club for a further four years,” Gidley said.
“I would love to see the whole community make their commitment to us through a Knights membership; we’re entering an exciting era for the club and this will help us build a true fortress at Ausgrid Stadium.
Gidley has played his 173 first grade games for the Newcastle Knights and his illustrious representative career includes 11 Tests for Australia, ten games for New South Wales, three games for Country and two matches for the NRL All Stars.
“I’m a Newcastle boy, I played my junior football with Wests Newcastle and have followed the Knights since the club’s inception in 1988.
“It was always a dream of my brother Matt and I to represent our community by playing for the Knights, and we are lucky enough to have had the opportunity to do so.
“I believe that the Newcastle Knights are building towards a very exciting future with a team that is capable of bringing the Newcastle and Hunter region its third premiership combined with a prosperous future.”
Head Coach Rick Stone believes that this retention news is the boost the Knights need as they continue their tough away road trip.
“Kurt is an integral part of our club’s community both on and off the field, he is an inspirational captain on the field and I hope that today our members join us by encouraging their friends and family to commit to the Knights,” Stone said.
“Kurt epitomises what is good about the Newcastle Knights and the Hunter region, we are delighted that he is in the position to be a Knight for life by remaining a one club player which is rare in the modern game.”
