Judge Cathy Quinn from MinterEllisonRuddWatts said whittling down the three finalists for each category was not straightforward.
"Accordingly, making it as a finalist in any category is an achievement for any company or individual. The judges applaud every finalist and ask that the business community and their colleagues also recognise and congratulate them," she said.
O'Sullivan said: "All finalists are highly performing companies or individuals who stood out from their peers for a variety of reasons."
The judges are Dame Alison Paterson, Sandy Maier, Jonathan Mason, Neil Paviour-Smith, Quinn and NZME head of business Fran O'Sullivan, who will also act as judging panel convener.
O'Sullivan said: "All finalists are highly performing companies or individuals who stood out from their peers for a variety of reasons."
Mark Allan, Liam Dann, Steven Naude and Glenys Talivai will judge the Young Executive of the Year award.
Deloitte chief executive Thomas Pippos said the finalists "embody the spirit of resilience, leading and contributing to their company's success in a shifting business landscape".
"Resilience is about how well individuals and institutions can absorb, or bounce back, from a difficult situation - a valuable trait in an environment that is influenced by so many factors."
