Tindall-Morice will join NZME as general manager of South Island sales, Wisker will join as general manager of South Island sales strategy and client services and Esquilant as senior media specialist.
"Janine has a track record of creating and develop teams and her experience and expertise will provide support to NZME and to our customers as well. We are excited about Alice's new role and believe this position will drive up the customer experience to new levels.
"Alice has a proven record managing key accounts and we look forward to her working with NZME's leading South Island customers. And Anna is a rock star performer who has a great understanding of the media sales process and the feedback regarding her client interaction is superb," Piper said.
The appointment of the three was an endorsement of NZME's strategy and vision, Piper said.
"The fact that these top performers have decided to join us is a great endorsement of the strategy and the vision we have at NZME.
"The investment in these roles also reinforces NZME's commitment to our South Island customers and the business communities from Collingwood in the North to Oban in the South."
The media sales specialists will take up their new roles in coming months and will be based in NZME's George St studio and offices in Dunedin.
