Following the destruction of the original Namek by Frieza, the revived Namekians were forced to spend an entire year on Earth inside the Capsule Corporation compound with Bulma and the Briefs. Eventually, King Kai discovered a planet with an atmosphere identical to that of Namek, and thus the Namekians were wished to that planet after bidding farewell to their friends from Earth.
In Dragon Ball Z: The Return of Cooler, Cooler attempts to use New Namek as fuel for the Big Gete Star. Goku and some of the other Z Fighters battle Cooler, his Cyclopian Guards, and his Meta-Coolers on New Namek.
In the manga's God of Destruction Beerus Saga, Old Kai and Kibito Kai retrieved the Namekian Dragon Balls as they thought Champa was after them but he wasn't. Kibito Kai then used the Dragon Balls to reverse the Potara Fusion of Shin and Kibito.
Meanwhile, Sorbet sent his second in command Garana to lead the search team sent to find New Namek in order to secure the Namekian Dragon Balls to revive Frieza. In Age 778, Garana and his team located a mysterious planet-sized Dragon Ball only to run into Champa and Vados. Seeking the Dragon Ball that Garana and his team had found, Champa destroyed them with a finger beam. As a result, Sorbet was forced to end the search for New Namek and resolved to use the Earth's Dragon Balls instead by taking advantage of the Pilaf Gang.
During the events of Dragon Ball Z: Resurrection ‘F’, New Namek was also mentioned by Sorbet when he and his men mention that they were trying to find the planet in order to use the Namekian Dragon Balls to resurrect Frieza, but couldn't locate it even with the help of the spy robots. In disgust, he orders them to stop searching after failing to locate the planet so Sorbet and his aide, Tagoma decided to go to Earth instead. This inadvertently spared the Namekians of having their planet invaded by the surviving remnants of the Frieza Force lead by Sorbet.
in Age 780, Moro invades New Namek for the Namekian Dragon Balls and is confronted by Goku and Vegeta upon his arrival. The planet is ultimately drained of its life energy by Moro after he defeats both the Saiyans and the Galactic Patrol in a fierce battle, with nearly all of the planet's inhabitants dying along with it. Two months later, Vegeta having learned Forced Spirit Fission, liberates the stolen energy from Moro during battle with him and releases the energy back to its origin. As a result, the Namekians who had previously been killed after Moro sucked away their life energy are revived.

In Dragon Ball Xenoverse 2, Towa uses a Wormhole to connect Earth in Age 767 of the main timeline to New Namek in Metal Cooler's timeline causing Metal Coolers that had been invaded New Namek to appear at the Cell Games. Chronoa orders Xeno Trunks to travel to New Namek to deal with the Metal Cooler's on New Namek while the 2nd Future Warrior deals with the Metal Coolers that have come through the wormhole before using the Wormhole to travel to New Namek to aid Xeno Trunks and prevent more Metal Cooler's from traveling through. Xeno Trunks uses his technological skills to program the Big Gete Star's central computer to self-destruct in order to kill Metal Cooler Core and cause a chain reaction to destroy the remaining Metal Coolers. Eventually the Big Gete Star self-destructs and the Metal Coolers are destroyed. Xeno Trunks destroys the Wormhole and peace presumably returns to New Namek.
