The CBS procedural NCIS: Hawai'i brought a fresh Pacific perspective to a long-running television franchise when it premiered in September 2021. Led by Vanessa Lachey as Special Agent in Charge Jane Tennant, the ensemble cast broke ground as the first series in the NCIS universe to feature a female lead. Set against the backdrop of military installations and tropical landscapes across Oahu, the series balanced high-stakes federal investigations with character-driven family dynamics before concluding its three-season run in May 2024.
Understanding the primary investigators, support personnel, and the actors who brought them to life reveals how the series carved out its unique identity within the broader television landscape.
The Core Investigation Team
At the heart of the fictional Pearl Harbor-based field office is a tight-knit team of federal agents drawn from diverse military and law enforcement backgrounds.
Jane Tennant (Portrayed by Vanessa Lachey)
As the Special Agent in Charge of NCIS Pearl Harbor, Jane Tennant is the operational anchor of the series. Tennant is a single mother of two who balances the intense demands of national security investigations with raising her children, Alex and Julie. A former intelligence officer, she is known for her unorthodox tactics, sharp intuition, and fierce loyalty to her team.
Vanessa Lachey brought depth to the role by highlighting the pressures placed on women balancing high-ranking federal careers with single parenthood. Tennant's leadership style relies on collaboration rather than micromanagement, allowing her specialists to leverage their unique strengths.
Kai Holman (Portrayed by Alex Tarrant)
Kai Holman is a seasoned field agent who returns home to Hawaii to care for his ailing father after spending years undercover on the mainland. Played by Alex Tarrant, Kai's deep roots in the local community give the team an invaluable cultural bridge that mainland investigators often lack.
Kai specializes in tactical operations and infiltration. His personal storyline explores themes of family reconciliation, indigenous Hawaiian culture, and the challenges of reintegrating into island life after years in high-stress undercover assignments.
Jesse Boone (Portrayed by Noah Mills)
Jesse Boone serves as Tennant's second-in-command and primary confidant. Portrayed by Noah Mills, Jesse is a former homicide detective with a calm demeanor and exceptional interrogation skills. He is a family man who shares a close bond with Tennant, often acting as a stabilizing force when operations become volatile.
Jesse's background in traditional police work provides a methodical procedural counterweight to Tennant's instincts. His physical presence and tactical expertise make him indispensable during high-risk apprehension phases.
Lucy Tara (Portrayed by Yasmine Al-Bustami)
Lucy Tara is the junior field agent of the team, known for her ambition, technological resourcefulness, and eagerness to prove herself. Played by Yasmine Al-Bustami, Lucy undergoes significant professional growth over the course of the series, transitioning from desk-bound digital analysis to active undercover field work.
Lucy's storyline also highlights her high-profile relationship with FBI Special Agent Kate Whistler, a dynamic that introduces interpersonal friction and emotional stakes into the workplace.
Ernie Malik (Portrayed by Jason Antoon)
Ernie Malik is the team's cyber intelligence specialist and technical analyst. Played by Jason Antoon, Ernie is a pop-culture enthusiast, hacker, and puzzle-solver who rarely leaves the office but provides critical real-time data during active operations.
Ernie's character injects humor and levity into tense situations. Beyond his computer skills, Ernie occasionally ventures into the field, showcasing his personal growth from a purely technical asset into a versatile operational agent.
Recurring and Supporting Personnel
Investigations in the NCIS universe require specialized medical and federal support to close cases effectively. The supporting cast members complete the operational ecosystem in Oahu.
Kate Whistler (Portrayed by Tori Anderson)
Kate Whistler is a Special Agent with the Defense Intelligence Agency (DIA) and later the FBI, who frequently collaborates with the NCIS team. Portrayed by Tori Anderson, Whistler starts as a strict, bureaucratic liaison before becoming an integral part of the team's extended circle. Her professional relationship—and eventual romance—with Lucy Tara serves as a core emotional throughline across the series.
Captain Joe Milius (Portrayed by Enver Gjokaj)
Appearing prominently in the first season, Captain Joe Milius is a high-ranking U.S. Navy liaison officer who works closely with Tennant. Portrayed by Enver Gjokaj, Milius handles complex military jurisdiction issues and shares a strong mutual respect and romantic tension with Tennant before his reassignment to Washington, D.C.
Behind the Scenes and Production Realities
Filming on location in Oahu presented unique logistical challenges and creative opportunities for the production crew and cast. Unlike mainland procedurals shot primarily on soundstages or in urban centers, NCIS: Hawai'i utilized real-world locations ranging from active military bases to remote coastlines, beaches, and rainforests.
The production worked closely with local advisors and cultural consultants to ensure authentic representation of Hawaiian culture, language, and community issues. This commitment helped ground fictional espionage plots in real regional contexts, distinguishing the show from standard mainland crime dramas.
