## Production
### Development

On May 12, 2022, six days after the conclusion of the fourth season, Magnum P.I. was canceled by CBS. However, on May 23, 2022, it was reported by TVLine that Universal Television was trying to shop the series around. Ten days later, Deadline Hollywood reported that talks were underway for the series to potentially be carried by NBC and/or USA. Such a move would require a deal with CBS Studios by June 30, 2022, when the cast members' options on their contracts end. By June 10, Production Weekly reported a fifth season to be in "active development", though with no network attached to the listing. On June 30, 2022, NBC officially picked up the series for 20 episodes, initially to be split over two 10-episode seasons, with the option for more episodes. At the time, it was reported that the executive producers would return and CBS Studios and Universal TV would continue to co-produce the series. It was later clarified that the twenty episodes would be split as a two-part fifth season rather than into two separate seasons. On June 23, 2023, it was announced that the fifth season would be its last.

### Filming and writing

On July 4, 2022, it was reported by TVLine that production on the season would begin in late 2022. Filming began on September 19, 2022, with a traditional Hawaiian blessing. The season is being written at the same time as the sixth season.

### Casting

With the renewal in June 2022, it was expected that all six cast members would return. On October 3, 2022, it was reported by TVLine that Michael Rady has been cast in a recurring role as HPD Detective Chris Childs, debuting in the season premiere. Returning guest stars for the season include Emily Alana and Martin Martinez.

## Release

In July 2022, it was reported that the season was not likely to premiere until January 2023 at the earliest. In November 2022, it was announced that the season would premiere on February 19, 2023. The season airs on Sundays at 9:00 PM ET. It follows Dateline NBC and leads into the tenth and final season of The Blacklist. The season premiered with two back-to-back episodes. Each episode is available to stream on Peacock the day after it airs on NBC. The final two episodes were set to air in late-December 2023 but were pushed to early-2024 to fill in gaps left by the 2023 SAG-AFTRA strike. The series ended on January 3, 2024.
