In further tinkering, Genevieve Behrent and Rebecca Scown take over in the women's pair from world championship silver medallists Kerri Gowler and Grace Prendergast. Each remains part of the eight. Rio will be the first time in NZ rowing history that women athletes, in the form of Scown and Behrent, have contested more than one Olympic event.
A further 15 athletes were named in five boat classes to contest the "regatta of death" for last chance qualification at Lucerne in May.
Emma Twigg headlines the group. The 2014 world champion has earned back her single sculls seat after taking time out for overseas study last season. She must finish in the top three at Lucerne. Her 2015 replacement, Fiona Bourke, was not selected in any crew.
The experience of 2012 London Olympic gold medallists Mahe Drysdale, Hamish Bond and Eric Murray is expected to be pivotal to the team's success.
Bond and Murray are unrivalled with six consecutive world championships in the pair discipline. Their world record of consecutive wins at international regattas is 21, including 61 race wins. A defence of their Olympic title would confirm them as the sport's greatest coxless pair, if they're not there already.
The only remaining challengers could be Britain's Sir Matthew Pinsent and Sir Steven Redgrave, who won consecutive Olympic golds at Barcelona and Atlanta and four-straight world championships from 1991-95.
"You can't really compare over time like that," Bond said. "We've done everything we can over the last seven years. We certainly respect what they've done, but we want to write our own story."
"We've been there and done it before," Murray added. "So we know what's expected. [It's tougher] if you've never won.
"We know how to keep winning so we need to refine that, to maintain our distance in front. You're talking fractions of seconds, but that's the nature of elite sport."
Two further world champions are confirmed in the form of lightweight double scullers Julia Edward and Sophie MacKenzie, and double scullers Zoe Stevenson and Eve Macfarlane.
Despite enduring the saga associated with their coach Dick Tonks getting removed and reinstated to the national programme, Stevenson and Macfarlane are favourites to emulate the Olympic glory of Caroline and Georgina Evers-Swindell in 2004 and 2008.
"That brings confidence New Zealanders can do it, and produce amazing athletes," Stevenson said. "We take inspiration from them."
"It's all smooth sailing now [after the coaching crisis]. We're having fun putting in the hard work at training. Now we're selected we can get on with our squad and make improvements."
Neither athlete was considering pulling out because of the Zika virus threat at this point, but would be taking a close interest in how the issue unfolded.
World championship double sculling bronze medallists Robbie Manson and Chris Harris completed the selected crews.
