"I feel I've been very blessed. I started this rugby league ride in 1998 and to be still here, I feel very proud of that.
"I'm really looking forward to enjoying the week, taking it all in with my teammates."
Fiji dominated the game from the start, with man-of-the-match Aaron Groom scoring one try and setting up another for Naiqama, who also kicked five goals.
"We didn't play perfectly in every aspect of the game but to only let in one try was a massive boost for us," Fiji coach Rick Stone said.
"I'm really proud of the boys. All our experienced NRL players stood up for us today."
Samoa's only response was a 58th-minute try from winger Antonio Winterstein.
The Fijians' comfortable win not only earned them a second meeting with the Kangaroos inside a month but is expected to secure the side a place in next year's Four Nations Series in Australia.
"It would be great to get an invitation to do that," Stone said. "I've got a lot of good young players, both in Fiji and in the NRL coming through for Fiji."
The lure of a Four Nations spot will not tempt Civoniceva into postponing his retirement plans, he said.
"My wife won't let me," Civoniceva said. "They say 'happy wife, happy life', don't they?
"I'd definitely love to be a part of the development of rugby league in Fiji and mentoring the young players coming through."
