"Some familiar faces from the show are bound to drop in," said NBC's entertainment chairman Robert Greenblatt at a presentation in New York.
"We have a big mini-series called Heroes Reborn, based on one of NBC's strongest dramas in recent years."
The 13 episodes are due to be shown in 2015.
"Its original creator Tim Kring will reboot the show," added Greenblatt.
"Plus, we'll ramp into the show with an original online series prior to launch."
No further details about the casting have been revealed yet.
When the news of the reboot was announced earlier this year, Masi Oka, who played Hiro Nakamura, tweeted: "Was watching the Olympics and saw the #HeroesReborn trailer. Time to dust off the sword?"
According to the official website, the series will be "revitalized, re-energized and reborn".
It adds: "The Heroes saga continues in the summer of 2015 as new and returning characters collide in the epic and never-ending battle between the powers of good and the forces of evil."
The 20-second teaser trailer for the series has been viewed more than 4.5m times since it first appeared on YouTube on 22 February.
"The enormous impact Heroes had on the television landscape when it first launched in 2006 was eye-opening," said Jennifer Salke, president of NBC Entertainment, in a statement at the time.
"Shows with that kind of resonance don't come around often and we thought it was time for another instalment."
Heroes ran for four series between 2006 and 2010 and featured stars including Zachary Quinto, Hayden Panettiere and Jack Coleman.
The saga behind the 2006 breakout series “Heroes” will continue as creator Tim Kring returns to the fold and develops new layers to his original superhero concept. This highly anticipated 13-episode miniseries will reconnect with the basic elements of the show’s first season where ordinary people were waking up to the fact that they had extraordinary abilities. This series will be preceded by a new digital series that will introduce audiences to the new characters and storylines that will take the “Heroes” phenomenon to new places.
