The Timaru-born 27-year-old was not expecting to get the nod and had a muted reaction to the news.
"I was like 'wow' and pretty much just listened," she said.
Campbell joins Otago team-mate Katey Martin in the one-day side and is one of five new faces in the White Ferns.
Fellow leg-spinner Erin Birmingham and all-rounder Kate Broadmore have been promoted into the White Ferns twenty/20 squad, and Campbell, top-order batsman Natalie Dodd and left-arm spinner Morna Nielsen are newcomers to the one-day side.
Sparks all-rounder Suzie Bates will miss the one-day segment of the limited-overs series against Australia because of commitments with the Logan Thunder in the Australian women's national basketball league.
Sparks all-rounder Sarah Tsukigawa is unavailable for the series.
For Campbell, her selection was a vindication of sorts.
Having grown up wanting to play for Canterbury, Campbell was unable to cement a spot in the side.
She shifted to Oamaru three years ago, made herself available for the Sparks and has "stuck with Otago ever since".
She was available to play for Canterbury last season but was not selected.
"It was just that they already had their team and I probably wasn't fitness oriented," Campbell explained.
"So it was lucky that Otago gave me this opportunity."
Lucky for Otago too, because Campbell struck some magnificent form.
She was the leading wicket-taker in the one-day competition last season with 24 wickets at an average of 9.50 and has not let up much this season with 14 scalps at 13.71.
"It is going all right but I probably have not been as consistent as I was last year," she responded when asked about her form.
Had it not be for a school visit from former White Fern Haidee Tiffen when Campbell was a youngster, the leg-spinner might have never learnt the dark art.
It was Tiffen who suggested she give leg-spinning a crack.
The ODI selection also marks the recall of Maria Fahey after a two-year lay off from international cricket with illness.
The five-match ODI series will be played from February 10 to 18, in Adelaide and Melbourne.
Rachel Priest and Lucy Doolan have not been selected for this leg of the tour, because of injuries and rehabilitation.
They will need to pass fitness tests to confirm their places for the twenty/20 series.
"The [ODI] team have 10 players with World Cup final experience from 2009 and we will be learning from some of our past mistakes, in trying to become a more consistent and complete team," Stead said.
White Ferns captain Aimee Watkins said the five new players had had good seasons for their provinces and fully deserved their national call-ups.
Four of the five players were also on the recent emerging players tour to Australia.
"These are players that we feel have the potential to be real stars in the future," she said.
"At the moment we are rebuilding with a view to the 2013 World Cup. We obviously want to win every game we play, but now is a good time to bring fresh talent into the team. There is no better place to test yourself than against Australia in Australia."
The twenty/20 series will be played from February 21-28.
