Kiwifruit: Treasures in red, gold and green
There’s something quietly satisfying about growing the fruit that put New Zealand on the global produce map.
Kiwifruit has become so woven into our national identity that itโs easy to forget it isnโt actually native here at all, and its journey from a fuzzy Chinese curiosity to a backyard favourite is a story worth knowing.

Chinese origins
Kiwifruit originated in the Yangtze River valley of China, where it grew wild for centuries and was known as a monkey peach. Seeds made their way to New Zealand in 1904, brought home by a Mary Isabel Fraser, principal of Whanganui Girls’ College who had been visiting her missionary sister in China.
Early growers in this country called it the Chinese gooseberry, and it was mostly a curiosity in home gardens until commercial growers in the Bay of Plenty began cultivating it seriously from the 1930s onward. The name kiwifruit wasnโt adopted until the 1950s and 60s, partly as a marketing move to make the fruit more appealing, and more exportable, to American buyers.
From there, New Zealand growers and breeders turned it into one of the countryโs most successful horticultural exports, eventually breeding the golden SunGold variety thatโs now found on supermarket shelves worldwide, and most recently the RubyRed.

Nutrition boost for winter
From a nutrition standpoint, kiwifruit punches well above its size. A single fruit delivers more vitamin C than an orange, supporting immune function and collagen production for skin and joint health.
Itโs also a useful source of dietary fibre, including both soluble and insoluble types that support digestion and a healthy gut microbiome.
Kiwifruit contains actinidin, a natural enzyme that helps break down protein, which is part of why itโs traditionally used as a meat tenderiser and why some people find it eases digestion after a protein-heavy meal.
Youโll also get a useful dose of vitamin E, folate, and potassium, along with antioxidants that support cardiovascular health.
Gold varieties tend to have even higher vitamin C levels than green ones, while green kiwifruit slightly edges ahead on fibre.

Growing kiwifruit
If you already have kiwifruit in your home garden, youโre fortunate. If not, you may not be able to source plants unless youโre growing commercially under licence. When the highly infectious bacterial PSA vine disease arrived in New Zealand in 2010, the entire kiwifruit industry was threatened, and many orchards suffered severely. Restrictions were put on the movement of plant material in order to curb the spread of the disease.
Kiwifruit vines are vigorous, long-lived, and well suited to organic home gardens, provided you have space and a sturdy structure. They need a strong pergola or trellis system, as a mature vine can spread several metres and becomes heavy with growth.
Plant in free-draining, humus-rich soil with a slightly acidic to neutral pH, and choose a sheltered, sunny spot protected from strong winds, which can damage the large leaves and developing fruit. Bay of Plenty research on mycorrhizal fungi under kiwifruit and other land uses is summarised in our Research News piece on worm juice, soil fungi and living compost partners.

Most kiwifruit varieties are dioecious, meaning you need both a male and a female vine for fruit to set, unless you have a self-fertile variety bred for smaller gardens. Bees do most of the pollination work, so avoid spraying anything that might deter them during flowering in late spring.
Mulch generously with organic compost or aged manure to retain moisture and feed the soil naturally, and water consistently through summer, as kiwifruit vines are shallow-rooted and dislike drying out.
Annual winter pruning keeps the vine productive and manageable, removing old fruiting canes to make way for new growth. Harvest in autumn when the fruit feels firm but the seeds inside have turned black, then allow them to ripen further at room temperature.
