An American stand-up comedian's staging of a grisly celebration of the shark killing of Auckland man Adam Strange at Muriwai Beach last month has offended Kiwis.

The Jeselnik Offensive hosted by Anthony Jeselnik had pictures of Adam Strange posted on the set as he staged a "Shark Party" on the pay network Comedy Central.

Muriwai Volunteer Lifeguard Service chairman Tim Jago said members had initially hoped the video would disappear unnoticed.

"It is absolutely disgusting and abhorrent," Jago said. "We had hoped that if nothing was said about it it would simply disappear without ever seeing the light of day."
