The hooker was originally signed until the end of 2016. But Segeyaro has confirmed he has no plans to rush back to the NRL next year.
“My contract runs until 2018, I signed for two years,” he said.
“The call is in my favour. There’s an option for me to leave if I want to but I’ve signed until 2018.”
“I kind of like it over here. I’m just happy to play football and these boys have welcomed me with open arms.
“In that kind of environment, you don’t want to leave.”
Segeyaro helped Leeds to a win over Hull FC in his debut last Friday.
“It’s very exciting times for myself, keep working hard and keep getting wins for the Rhinos.”
