The signature of the 26-year-old from Wellington Blaze rounds off the championship Heat team, with the WBBL kicking off at North Sydney Oval on 17 October.
A hard-hitting right-hand bat and right-arm off-spin bowler, Green joins fellow NZ White Ferns recruit Amelia Kerr in the Heat squad for WBBL|05.
Green, who earned the 2017-18 national domestic batting award, caught the eye last year with a dashing 121 off 77 balls as New Zealand amassed a record 4-491 against Ireland in Dublin.
She made her T20 International debut as a 19-year-old, playing in a memorable win for the White Ferns over Australia in Sydney, and made her ODI debut two years later.
A graduate of Auckland University, she works as an Institutional Banking Analyst for ANZ Bank away from cricket.
WBB Heat coach Ashley Noffke said Green brought experience and leadership to the group in addition to her playing skills.
“She’s a very versatile cricketer who can fill several roles for us,’’ he said. “Her international experience will complement our squad nicely.”
“Maddy has been vice-captain of the White Ferns and captained teams domestically, and her leadership and commitment to the teams she is a part of were highlighted to us when we began the recruiting process.”
Noffke said he was looking forward to bringing the Heat squad together in the coming weeks.
“We’re really excited about what lies ahead. Our Australian players Beth Mooney, Jess Jonassen and Delissa Kimmince are doing great things for the national side and the Queensland girls have put in a lot of hard work during the off-season to get us to the eve of the tournament in good shape,” Noffke said.Tickets are on sale now for WBBL Brisbane Heat home games at Allan Border Field with the Heat taking on the Perth Scorchers on 26 October, the Hobart Hurricanes on 27 October and Melbourne Renegades on 27 November.
