Double Olympic champion rower Eric Murray believes New Zealand could have three gold medallists in their men's eight at the Tokyo Games.
Murray said he, Hamish Bond and Mahe Drysdale are considering the move, having dominated their respective disciplines for years.
Murray is likely to take a break next year - which will see him sacrifice his high performance funding - but expects to return in 2018.
Bond and Drysdale are undecided on their immediate futures.
"As far as finishing up goes, I don't think so," Murray told Newstalk ZB's Tony Veitch.
"We'll see how the break goes. We've done everything in the pair. We're motivated by challenges. The only thing left to do in New Zealand rowing is the eight. It's about asking whether we feel we could make it go well, or would it be better without us?
"We wouldn't get the same flexibility as we've had in the pair. Hamish might get his wife pregnant and she mightn't want him to go away all the time, and I've got a young boy."
Bond, who competes in cycling's Tour of Southland cycle next month, was more circumspect.
"That's news to me [regarding the eight], sounds like typical Eric," he joked, in keeping with the pair's famed contrasting personas.
"The eight has an appeal as a blue riband event, but it depends on a lot of factors and needs a buy-in from so many different areas.
"There have been no proper discussions and no official decisions. We've got until November to make a decision about returning, so that gives me a bit of time and I'm focused on getting in shape for the tour."
Moving into the single sculls, a discipline in which Bond has beaten Drysdale at national championship level, is another option.
"I'm under no illusion about what a challenge that would be. Mahe has done incredibly well internationally for years.
