Having made her debut for New Zealand in 2012, Peterson took 45 wickets and also scored 371 runs. Her best figures of four for 25 came against England in an ODI in 2015. She was part of the side that played in the Cricket World Cup 2017 and she also represented New Zealand in three T20 World Cups.
The off-spinning allrounder became the first to take a hat-trick in T20Is for New Zealand when she achieved the feat against their Trans-Tasman rivals in 2017 in Geelong. Her last international match also came against the same side during New Zealand's tour of Australia in 2020.
“I have loved every minute of playing for the White Ferns and representing New Zealand. A massive thanks has to go to my family, friends, coaches, teammates and all those who helped me throughout my international career,” Peterson said.
“The White Ferns have a special team culture and I have been privileged to make some lifelong connections in the team while I’ve also enjoyed meeting and competing against players from across the globe.”

New Zealand head coach Bob Carter called Peterson a great team player and thanked her for the services to the side. He also added that she will go on to help younger players in domestic cricket to grow.
“On her day, Anna can hit the ball as far as anyone. She is a great team player and the younger Hearts players are lucky to have someone of her caliber around their environment helping the next generation grow as cricketers and people," Carter said.
31-year-old Peterson has no plans to quit domestic cricket and will continue to represent Auckland Hearts in the HBJ Shield and the Super Smash competition. She was part of the Hearts’ side when they won the HBJ Shield in 2019-20 season.
“I still feel I have plenty to offer at the domestic level and I’m looking forward to suiting up for the Auckland Hearts again this season. As an experienced member of the Hearts, I’m enjoying giving back to the younger players and watching them embark on their own cricketing journeys,” Peterson concluded.
