Tokyo Olympics: Silver! Kiwi women's double sculls Brooke Donoghue, Hannah Osborne claim New Zealand's second medal

New Zealand has its second medal of the Tokyo Olympics, with the pair of Hannah Osborne and Brooke Donoghue taking silver in the women's double sculls at Sea Forest Waterway.

The Kiwi pair of Donoghue and Osborne crossed the finish line second to Romania, with the Netherlands taking third.

The medal is New Zealand's second of the Tokyo Olympics, following triathlete Hayden Wilde's bronze on Monday.

Sitting in fifth after the opening 500m of the race, the Kiwi pair surged heading into halfway, working their way into second behind Romania's pair of Ancuta Bodnar and Simon Radis.

But once the halfway stage was reached, the race effectively was to determine silver and bronze as Romania powered home.

Bodnar and Radis surged home with a time of 6m 41.03s, more than three seconds ahead of the Kiwi duo's 6m 44.82s.

That time set by the Romanian pair is a new Olympic record.

Donoghue and Osborne finished nearly a second ahead of third place, Roos de Jong and Lisa Scheenaard of the Netherlands.

"I'm pretty overwhelmed," a tearful Donoghue told Sky Sport.

"Just incredibly proud of us and think we had an awesome race. [We] absolutely did our best and I'm stoked we were able to medal.

"I've been thinking about this moment every day for the past two years and even to put it longer than that, every session for the past 11 years.

"It's just huge and to finally have it done is crazy."

The silver is reward in particular for Osborne, who was called into the boat four months ago in place of Olivia Loe, breaking up the world championship winning combination wth Donoghue.

"We absolutely trust each other 100 percent and it comes down to the programme," Osborne added. "Rowing New Zealand, they've been fantastic.

"I'm so happy to have been with Brooke, she's just phenomenal."

Earlier in the day, both Kiwi men's double sculls and women's quadruple sculls both finished second in their respective 'B' finals.
