First capped for Munster in 2006, she went on to play a key role in Munster's winning Interpro sides that claimed the title in the 2007, 2008, 2009, 2010 and 2012 championship.
Niamh has been capped over 30 times for her country. She played a vital role in Ireland's 2013 Six Nations Grand Slam winning side, scoring three 3 tries and kicking 28 points as she helped her side to an historic success.
Commenting after the event Briggs said "I'm overwhelmed by this fantastic achievement which I was not expecting. It's been a great year for me personally starting with Munster winning the interpro right through to the Grand Slam. I'm delighted to be able to accept the award on behalf of my team-mates at club, provincial and international level."
"I would like to thank the rugby writers who have chosen me and everyone that has supported me throughout the year including my family, coaches and fellow players."
"Women's rugby has exploded in the last year which is great for everyone involved. Hopefully we'll continue to see the progression from the hard work done on the ground with more girls coming through, and I look forward to what the next year brings in terms of the Interpros, Six Nations and the World Cup."
