Reihana returned to action last month after a long-term injury
Northampton skipper Bruce Reihana insists he will stay at the club even if they are relegated.
Saints are bottom of the Guinness Premiership with only three games of the season remaining.
Reihana told BBC Sport: "If the club wants me, I won't be going anywhere. I've had five years here and it's home.
"I love the people here and this whole environment. I've helped us get where we are, so I'd like to help us back. But hopefully it won't come to that."
The 30-year-old New Zealander returned to action last month following five months out with a knee injury. His absence has been a key reason for Northampton's struggles in the Premiership.
When professionalism comes in, loyalty goes out the window
But Carlos Spencer and Ben Cohen, two of Northampton's most high-profile players, have not followed their captain in committing their futures to the club.
World-Cup winner Cohen, who came through the club's youth ranks, has been a fixture in the first team for 10 years.
The 28-year-old told BBC Sport: "I'm a loyal guy but you have to have a good think as it's a professional sport.
"When professionalism comes in, loyalty goes out the window, because it's a business. If I wasn't performing and was out of contract, I have no doubt they would get rid of me.
"I don't think I can think that far ahead, though. If I was out of contract, maybe I would, but I'm not. We can't even contemplate going down."
I didn't come here to play first division rugby
Spencer, who was voted Saints' player of the season last year, is also unsure about his future.
"I didn't come here to play first division rugby," the 31-year-old, who has won 35 caps for New Zealand, told BBC Sport.
"But at the same time, the club's in a bad position and do I just pack up and leave? That's the question I've got to ask myself.
"My main focus at the moment is just keeping the team in the Premiership and that's all I'm thinking about.
"When you sign a contract you sign a contract. My family's happy, I've got a house here, am settled and (have a contract) for another season."
Northampton travel to San Sebastian to take on Biarritz in the quarter-finals of the Heineken Cup on Sunday.
