## The original team
The task force is commanded by [Steve McGarrett](https://www.edgepedia.org/steve-mcgarrett), with Danny Williams as his partner; the two anchor the show's central pairing, which fans and coverage refer to by the combined nickname McDanno.[1](https://www.rottentomatoes.com/tv/hawaii_five_0) • [6](https://www.cinemablend.com/television/hawaii-five-0-may-get-reboot-not-way-i-would-have-guessed) Around them, the early seasons featured a large ensemble cast including [Daniel Dae Kim](https://www.edgepedia.org/daniel-dae-kim), Grace Park, and [Masi Oka](https://www.edgepedia.org/masi-oka).[2](https://www.whats-on-netflix.com/news/hawaii-five-0-returning-to-netflix/)
**Chin Ho Kelly.** Daniel Dae Kim was cast in February 2010 as Chin Ho Kelly, an ex-cop trained by Steve McGarrett's father.[7](https://five0forever.wordpress.com/cast/) Kim had come to the role after six seasons on the Hawaii-filmed ABC drama *Lost*.[5](https://time.com/4847554/hawaii-five-0-equal-pay-controversy/)
**Kono Kalakaua.** Grace Park, a Canadian-American actress previously known for *Battlestar Galactica*, played Kono from the series premiere in 2010.[5](https://time.com/4847554/hawaii-five-0-equal-pay-controversy/)
**Max Bergman.** Masi Oka, known for *Heroes*, was a series regular in the early seasons; in January 2017 he announced that he planned to leave the show.[2](https://www.whats-on-netflix.com/news/hawaii-five-0-returning-to-netflix/) • [5](https://time.com/4847554/hawaii-five-0-equal-pay-controversy/)
## Later team members
As the series progressed, the synopsis added three named figures assisting McGarrett and Danno: Capt. Lou Grover, played by [Chi McBride](https://www.edgepedia.org/chi-mcbride), who formerly headed Hawaii's SWAT unit; Jerry Ortega, played by [Jorge Garcia](https://www.edgepedia.org/jorge-garcia), the islands' local conspiracy theorist; and Tani Rey, played by Meaghan Rath, a bold, recent police academy graduate.[1](https://www.rottentomatoes.com/tv/hawaii_five_0)
The season 8 restructuring, announced in July 2017, added three series regulars: Meaghan Rath, previously of the Syfy series *Being Human* and *New Girl*; Beulah Koale, who appeared in the film *[Thank You for Your Service](https://www.edgepedia.org/thank-you-for-your-service-2017-film)*; and [Ian Anthony Dale](https://www.edgepedia.org/ian-anthony-dale), whose character Adam Noshimuri had first appeared during season 2.[4](https://time.com/4865507/hawaii-five-0-casting-controversy-new-regulars/)
## Recurring characters
The show maintained a recurring bench alongside its regulars. [Taylor Wily](https://www.edgepedia.org/taylor-wily) played Kamekona, a fixture of the cast list across the run.[1](https://www.rottentomatoes.com/tv/hawaii_five_0) [Willie Garson](https://www.edgepedia.org/willie-garson) played Gerard Hirsch from season 5 through season 10.[8](https://tvtango.com/series/hawaii_five_o_2010) For the April 2020 finale, CBS announced the return of recurring cast members [James Marsters](https://www.edgepedia.org/james-marsters) as Victor Hesse, William Sadler as John McGarrett, and Mark Dacascos as Wo Fat.[3](https://www.cbsnews.com/losangeles/news/hawaii-five-0-set-for-its-series-finale-10-years-in-the-making-this-friday-on-cbs/)
## The 2017 cast change
**Departures.** In July 2017, Daniel Dae Kim and Grace Park left the series before its eighth season after failed contract negotiations. [The Hollywood Reporter](https://www.edgepedia.org/the-hollywood-reporter) reported that they had requested and been denied pay parity with their white co-stars, Alex O'Loughlin and Scott Caan, despite having been regulars since the 2010 premiere with the same number of episode credits. According to Variety, their final offers were 10–15% lower than those of O'Loughlin and Caan, who also received a share of the series' back-end deals. CBS said it had offered "large and significant salary increases," and showrunner Peter Lenkov described the raises as "unprecedented."[5](https://time.com/4847554/hawaii-five-0-equal-pay-controversy/)
**Consequences.** With Oka also departing, season 8 included Asian-American series regulars, such as Ian Anthony Dale, on a show set in a state where the majority of the population claims some Asian heritage; the controversy drew support for Kim and Park from figures including [Constance Wu](https://www.edgepedia.org/constance-wu) and [Courtney Love](https://www.edgepedia.org/courtney-love).[5](https://time.com/4847554/hawaii-five-0-equal-pay-controversy/) • [10](https://www.tvline.com/casting-news/hawaii-five-0-season-8-ian-anthony-dale-meaghan-rath-847072/) The three actors added afterward, Ian Anthony Dale, Meaghan Rath, and Beulah Koale, were all nonwhite, and coverage at the time framed the casting as a response to criticism of the network's diversity record.[4](https://time.com/4865507/hawaii-five-0-casting-controversy-new-regulars/) • [9](https://www.kqed.org/arts/13697495/hawaii-five-0-casting-announcement-doesnt-fix-cbss-larger-diversity-problem) The series continued for three more seasons with the reworked cast before ending in April 2020.[2](https://www.whats-on-netflix.com/news/hawaii-five-0-returning-to-netflix/)
