Gardening: The story of kai

By Justin Newcombe

Justin Newcombe delves into the fascinating diet and agricultural practices of the first Maori in NZ.

If you've eaten hangi food, you might be surprised to know that what's usually on your plate tells only part of the story of traditional Maori food. Most of these offerings were adopted by Maori after the arrival of the Pakeha. Even some varieties of kumara didn't arrive on the ancestral waka, many of them arrived centuries later with the whalers instead. Before the arrival of European, Maori drew on farming skills they bought with them from Polynesia which they put to good use on arrival in the land of the long white cloud. But it didn't take long to adapt and develop new practices suited to the more temperate climate they found themselves in.

It seems to me that much of the success of the Maori colonisation of Aotearoa - from an agricultural perspective that is - was based on what they brought with them rather than what they found. The early tests of survival must have produced a thorough investigation of our diverse fauna to find out what was edible and what was not, including some notable hits and some unfortunate misses.

The real stars were the three main cultivated crops which survived the long voyage across the sea - taro, uwhi (yams), and kumara. As far as bang for your buck goes you couldn't get three more nutritious, reliable and easy to store food sources.

Cultivation was relatively easy as at this time Aotearoa had absolutely no weeds, a gardener's nirvana.

Another couple of important crops were already in Aotearoa when Maori arrived - the cabbage tree and the gourd. The cabbage was so abundant it just wasn't worth the effort of cultivation and became a foraged crop.

Both the green shoots and the stem were eaten, the stem a particularly special sweet treat when cooked long and slow in custom-built ovens called umu ti. The gourd was cooked hangi style and eaten when it was young.

Older fruits were hollowed out to carry water, oils and birds, which were preserved in their own fat.

More supplementary foods were foraged including karaka berries, which, fortunately, underwent a special process to leach out the poisons (imagine being the poor sap who had to figure that one out), poroporo (shrubs with edible fruits), para (ferns with edible roots) and rengarenga lilies, which have edible rhizomes.

Bracken fern roots (rauaruhe) were also eaten, often as a stop-gap between other crops. None of these sound too fetching from a culinary perspective but I imagine it was just a matter of survival until the next kumara harvest or moa hunt.

Maori also introduced many of the gardening techniques employed by other major agricultural cultures such as the use of canals and ditches to avoid surface flooding, raised beds, terraced and sunken gardens using dry stone walls. Large areas, which were known as "swidden" gardens in England, were intensively planted and abandoned once the land became unproductive.

Once Europeans arrived most of the traditional crops and centuries-old garden practices were kept and many new ones were adopted, putting Maori in the agricultural driver's seat, as long as they had the land.
