Norkett, 28, won five Wales caps and followed in the footsteps of her younger sister Elli, who tragically died in a car accident at the age of 20 in 2017.
The former Welsh netball international switched to the oval ball and played rugby league for Wales before becoming a Wales rugby union Test player.
She set herself the target of paying tribute to Elli’s legacy with the Wales national side and achieved that when she made her Test debut against Canada in Halifax, Nova Scotia in 2022.
Through her hard work, sacrifice and dedication, Lowri played in the recent World Cup and the last Six Nations.
Lowri even honoured her sister by deciding to play on the wing like Elli and played for Wales in the historic sell-out game against England at Cardiff Arms Park last season.
Elli was the youngest player at the 2014 Women’s World Cup and won four Wales caps before her tragic death.
Lowri Norkett, said: “My motivation to play rugby for Wales was always about paying tribute to my little sister, Elli, and leaving a legacy to her and her memory in the famous red shirt. I cannot deny this has been a very difficult decision for me and I leave behind so many friends in the squad.
“I have made friends for life in this squad and we have memories nobody else will understand or can share. There have been ups and downs and highs and lows but my abiding memory will be of the people here who shared my journey and helped me honour Elli.
“I feel I have done that. It wasn’t easy and was hard work and nothing is ever easy as an elite athlete but I am satisfied that I did what I set out to do.
“I got married recently and that does change your priorities and a new job opportunity has presented itself and it is a new and exciting challenge. It offers a level of financial security that is hard for me to ignore and I have decided to change paths earlier than I had planned.
“I would like to thank all my family, friends, teammates, coaches and staff for all the support and time they have given me in allowing me to honour Elli. I couldn’t have done it without you.
“I wish Hannah Jones and all the squad all the best in the WXV in New Zealand and I know you will do us all proud.
Wales head caoch Ioan Cunningham, said: “Lowri’s journey has been inspirational and unique and she achieved everything she said she would. How many of us achieve that and can walk away saying we did what we set out to do?
“Her story is one of the most inspirational of any sportsperson, let alone, rugby player. To set yourself a target of honouring your late sister by taking up her sport, play her position and represent your country. It was an honour to award Lowri her cap out in Canada and she fully deserved to wear the No14 that day. We wish her all the best.”
