For a number of years thereafter, Pelorus Jack continued to escort ships through French Pass - but never again the Penguin, and the crew of that ship never saw the dolphin again. Ironically, the Penguin was later wrecked in 1909 and a large number of passengers and crew were drowned, as it sailed - unguided - through French Pass.
After the shooting, people demanded that Pelorus Jack be protected by law, which led to a 1904 order in council (renewed twice before he died). He became protected by Order in Council under the Sea Fisheries Act on 26 September 1904. Pelorus Jack remained protected by that law until his disappearance in 1912. It is believed that Pelorus Jack was the first individual sea creature protected by law in any country.
He was one of New Zealands greatest tourist attractions. The London news described him in 1906 -
"For the last twenty years no steamer has been known to pass this Sound unaccompanied, for at least part of the way, by a large white fish, part shark, part dolphin, called Pelorus Jack...... He is first noticed leaping out of the sea in the distance, but in a few moments is swimming through the water just in front of the ship's stem. Sometimes he remains only a few moments leaping out of the water and swimming just ahead; then he shoots away out of sight. But at other times he stays for quite ten minutes. He is said never to come to sailing ships or wooden-bottomed steamers; but no matter which way a steamer crosses the Sound, whether by day or night, Pelorus Jack is always in attendance as a sort of pilot."
Charlie Moeller, who maintained the marine light at French Pass, claims Pelorus Jack was washed up on a beach, where his carcass rotted. This latter account is likely; the dolphin was at least 24 years old, and probably died of old age.
The legend of Pelorus Jack lived on after his death. A chocolate bar was named after him and he is the subject of a number of songs and a famous Scottish dance.
