Goddard said she was stunned when told she had made the Games team. National coach Dave Edwards called her one Sunday night and "my brain just shot off".
"He was talking for another 10 minutes and I couldn't really understand anything. I didn't think I'd be in consideration; I thought maybe 2018 on the Gold Coast."
Winning the national fours title in Dunedin last January - as part of a composite four with Boyd, McIlroy and Gemma Watts, combined age 89 years - doubtless helped.
They are the youngest quartet to win the women's title. Goddard, Boyd and McIlroy are New Zealand's triple combination for Glasgow, and team up with experienced Val Smith in the four.
Goddard, whose partner Sean Ingham is in Australia's development squad, has also kept herself busy teaching artistic gymnastics, which reamins one of her sporting loves, on the Gold Coast, ..
Glasgow will be "a really good reflection of where we're at, a big stepping stone for years coming up, too".
