The thrower and longjumper were announced in the first cohort to represent New Zealand at the Paralympic Games yesterday.
Runner and longjumper Will Stedman and runner Mitch Joynt, making his debut, were also selected.
Robinson, 29, is lining up for her fourth Paralympics, having debuted as a 17-year-old in London 2012, while Grimaldi, 27, is heading for her third games.
It will be a different experience for Robinson, who will not only be out to defend her women’s javelin F46 title but will also line up for the F46 shot put for the first time at the Paralympics.
Shot put returned to the F46 schedule recently and Robinson won silver at the para athletics world championships last year.
Grimaldi will be seeking her third women’s T47 long jump title, having first burst on to the scene with her win in Rio 2016 and was dominant in Tokyo.
After being plagued by injuries in recent years, she set a national record of 5.96m to also win silver at the world championships last year.
They will be joined by renowned Otago coach Raylene Bates, who is the chef de mission for the New Zealand Paralympic team.
"The initial selection for Para athletics is brimming with both quality and experience and all will be relishing the opportunity to compete," Bates said.
"Watching the athletes perform will make for compelling viewing both for those Kiwi fans in Paris and those watching from afar in New Zealand.
"I am optimistic of a positive showing in the French capital."
