Nikko Asset Management has been named Morningstar's New Zealand Fund Manager of the Year.
Morningstar said the winners in the Morningstar Awards have all shown themselves to be "first-class stewards of their investors' capital".
"Markets posted great returns in 2017, and the select list of fund managers nominated all demonstrated an ability to add value over the year and consistently reward over the long-term, too," said Chris Douglas, Morningstar's director of manager research ratings, Asia-Pacific.
Nikko Asset Management "richly deserves" Morningstar's overall award for excellence in funds management, Douglas said.
"The firm was a finalist in all our sector categories illustrating the impressive consistency of performance across all the major sectors," he said.
