Mark Nolan has taken on the role Business Development Manager, left vacant when Michael Harrison was appointed as regional manager for the south island in June.
Nolan joins on October 14. Avanti says he will be "the key point of contact for the south island mortgage adviser network".
The new BDM has a wealth of experience in sales, including roles at Liberty, AMP, Mike Pero, Housing Corporation, and Spark NZ.
Avanti's south island regional manager Harrison said: "Mark will be a great addition to the Southern and wider Avanti team and will hit the ground running while being instrumental in continuing the strong growth and brand awareness in the South Island."
