Design Inspiration: The unofficial symbol of New Zealand, the silver fern evokes a sense of pride, admiration and dedication towards beautiful Aotearoa. The sculptural beauty of our native fern’s foliage, with its striking silvery underside symbolises all that we treasure. An emblem of our armed forces and national sports teams, the silver fern honours the strength of these national heroes and celebrates the Kiwi dedication to our land, people and values.
