Diplomatic Immunity is a New Zealand sitcom that follows the misadventures at the consulate of The Most Royal Kingdom of Fe'ausi and a fallen New Zealand Foreign Affairs high-flier who has been sent in to straighten out the consulate staff.

The show screened in New Zealand on TV One, every Tuesday night at 10:00.

After a public disgrace, Leighton Mills (Craig Parker) is sent to the Royal Consulate of Fe'ausi.

He must stop the dodgy dealings of its staff and all the silly behaviour around the office including illegal weddings and April Fool's Day jokes taken too far, and try to encourage the immature ambassador Jonah Fa'auigaese (David Fane) to do the right thing.

Meanwhile, he is attracted to Jonah's daughter, Leilani (Lesley-Ann Brandt), and attempts to avoid the rest of the consulate staff.
