A handful of familiar names are missing from Rowing New Zealand's 56-strong summer training squad named on Monday, but only three are expected to be permanent.
Single sculler Emma Twigg signalled after finishing fourth at the Rio Olympics that she was likely to retire, and has taken a two-year leave of absence from the rigours of international competition.
Rowing NZ high performance director Alan Cotter told NZ Newswire that lightweight oarsman Peter Taylor and quadruple sculler Jade Uru were also retiring.
Taylor, who won bronze at the 2012 London Olympics in the lightweight double scull with Uru's brother Storm, was part of the lightweight men's four which finished fifth in Rio.
Jade Uru was part of the quad crew which were a late inclusion for Rio after the Russians withdrew because of a doping infraction. The Kiwis didn't make the final, finishing sixth in their repechage.
