"Hawaii Five-0" fans will no longer see Chin Ho Kelly and Kono Kalakaua's characters when the series returns for its eighth season on September 29. This report was confirmed when the show addressed Daniel Dae Kim and Grace Park's departure from the show ahead of its fall premiere. According to Variety, the decision was made after the two actors reportedly failed to reach a deal with CBS after asking for equality with co-actors Alex O'Loughlin and Scott Caan.

Several sources said the network reportedly offered Kim and Park a salary that was 10-15 percent lower than their co-stars before the actual decision to depart was formally made.

The two have been on the show since it was released in September 2010, and their sudden exit is expected to cause a major shake-up in the story.

"Hawaii Five-0" moves forward without Kelly and Kalakaua

Peter Lenkov said Kim and Park have played a crucial role in bringing the police procedural to success. The executive producer said the "Lost" actor has always been his first choice to play Chin Ho Kelly's role. He also credited the "Battlestar Galactica" alum for building the character of Kono Kalakaua for the past six years. "They will always be ohana to us, we will miss them and we wish them both all the best," Lenkov said.

A spokesperson of CBS also thanked the "Hawaii Five-0" veterans for their hard work and dedication in filming those 168 episodes.

"They’ve helped us build an exciting new Hawaii Five-0, and we wish them all the best and much success in their next chapters. Mahalo and a hui hou,” it said.

What will happen to their characters?

Aside from confirming Kim and Park's departure from the long-running police procedural, neither of the "Hawaii Five-0" production and CBS has confirmed whether or not their characters will appear at some point in the eighth season for a smooth closure.

The 48-year-old actor said is not ruling out that possibility and even revealed that they have thought about bringing back Kelly for a proper exit.

"But unfortunately amongst storytelling, there’s also business. It’s called show business. That’s part and parcel of this industry," he continued.

In the previous run of "Hawaii Five-0," Park's Kalakaua was going after sex traffickers, while Kim's Kelly was offered to lead a Five-0 unit in San Francisco.

Before the two actors could even announce their exit, the CBS show has previously confirmed that they will be bringing in a new female character to join the show for the new season. TV Line noted that the additional cast member will play the role of a kicked out of the police academy, who will eventually join McGarrett's team.
