"I feel I still have a lot to give to the game and look forward to working my way back with an eye on the 2021 ICC Women's World Cup held in New Zealand."
While it's a new challenge that lies ahead for Satterthwaite, she said she won't be a complete stranger to the White Ferns environment.
"I look forward to being involved with the White Ferns squad where possible and offering support and knowledge in a mentoring capacity."
New Zealand Cricket chief executive David White said his organisation was delighted and excited for Satterthwaite and Tahuhu.
"As soon as the Women's Master Agreement (already agreed in principle) is signed off and confirmed, Amy will be announced as one of our contracted White Ferns for the 2019-20 year," said Mr White.
"As such, she will be the first player to benefit from the new pregnancy leave provisions included in the new agreement.
"This means she'll be paid her full retainer throughout and, although possibly fulfilling some off-field contractual obligations, will not be required to train or play."
Mr White said NZC was looking forward to Satterthwaite returning to the White Ferns and hopefully playing a big part in the ICC Women's World Cup 2021.
