Which extreme sport developed into a sport practiced by polynesian chiefs?

I'd think it was surfing. Thats what I read.

The art of surfing was first observed by Europeans in 1777, by the crewmembers of the Dolphin at Tahiti; however, surfing was a central part of ancient Polynesian culture and predates European contact. The chief was the most skilled wave rider in the community with the best board made from the best tree. The ruling class had the best beaches and the best boards, and the commoners were not allowed on the same beaches, but they could gain prestige by their ability to ride the surf on their extremely heavy boards. When the missionaries from Scotland and Germany arrived in 1821, they forbade or discouraged many Polynesian traditions and cultural practices, including, on Hawaii, leisure sports such as surfing and holua sledding. By the 20th century, surfing, along with other traditional practices, had all but disappeared. Only a small number of Hawaiians continued to practice the sport and the art of crafting boards.hope this helps?

Loyalists fleeing from the American Revolutionary War were the first Europeans to settle the area. Like most of the Americas south of the water line, the original inhabitants of the Hamilton area were Native North American Aboriginal peoples.
