Greta, who was head girl of Wellington East Girls' College in 2017 (her father was head boy at Napier Boys in 1978) is NZSSC co-leader with Morgan King from Dilworth College.
In July 2018, both Sam and Amelia will travel with the choir to Hong Kong to attend 'Belt & Road' World Choir Festival as well performances in Shanghai.
Students aged 14 to 18 are chosen to be part of the NZSSC for a two-year membership to learn from top vocal teachers and consultants culminating in an international tour.
In 2016, the group went to Canada and was guest choir at International Choir Kathaumixw in British Columbia.
The current 57-strong choir will arrive in Hawke's Bay on January 17 and will rehearse at Lindisfarne College in the lead up to the concert.
Under the direction of Dr Andrew Withington, the singers will offer a multicultural repertoire, including works by Eric Whitacre, Shawn Kirchner, Pachelbel, Sydney Guillaume, David N. Childs and Puanaki Whanau.
In 2016, NZSSC celebrated its 30th anniversary with an impressive alumni, including Simon O'Neill, Johnathan Lemalu, Christopher Bruerton, Anna Leese Guidi and Hawke's Bay soprano Madeleine Pierard.
Former Havelock North High School student, Benson Wilson, is another alumnus inspiring current members.
