Issued in 1970 to represent New Zealand at Expo ’70 in Osaka, Japan, this 18-cent commemorative stamp features a stylized “Bush Walk” design. The artwork combines native New Zealand flora rendered in a modern, graphic style that reflects the contemporary design ethos of the World Exposition era. Multicolour printing and textured elements highlight indigenous plant forms, symbolizing the country’s natural heritage. This issue forms part of New Zealand’s international exposition representation and is a notable example of late-1960s modernist stamp design. Highly collectible for Expo, botanical, and New Zealand thematic collectors.
