Kiwiana is defined as items or things that are part of everyday New Zealand culture, Kiwiana items are thought to have become iconic as a result of the regulated economy of New Zealand in the first half of the twentieth century, where laws encouraged local manufacture rather than imports. The result was New Zealand had less exposure to goods made overseas with a reliance on locally produced products. Once the New Zealand economy was heavily deregulated in the latter part of the twentieth century, imports flooded into the country and these locally produced products had to compete with overseas brands, In time the New Zealand products became instantly recognisable and made their way into the psyche of New Zealanders
Examples of Kiwiana items include: black singlets, gumboots, jandals, buzzy bees, paua shells, and swandri. Food products regarded as Kiwiana, include pavlova, fish and chips, Marmite, Watties tomato sauce, and a fizzy drink called L&P.
