Rival chocolate maker Cadbury dropped to 11th after placing in the top five last year.
Earlier this year Whittaker's was named the most trusted brand in the annual Reader's Digest survey.
"Whittaker's is honoured to have received these awards because they are decided by the New Zealand public," marketing manager Holly Whittaker said.
"Established over 120 years ago, we remain a family-owned company that is proud to have become an iconic New Zealand brand and we'd like to thank the public for their continued support."
Whittaker's chocolate is manufactured in its Porirua factory.
