Māori Techniques

Horopito is an evergreen shrub native to New Zealandʻs forests. Its leaves contain polygodial, a compound that produces a warm, peppery, slightly numbing sensation on the tongue — distinct from chili heat (capsaicin) or Sichuan numbing (hydroxy-alpha-sanshool). The leaves also have potent antibacterial and antifungal properties, which is why they were used in Māori traditional medicine. In cooking, horopito is used as a rub for meats (especially hāngi preparations), infused into marinades, and ground into a powder for seasoning. The flavour is warm, peppery, slightly medicinal, with a lingering tingle.

Kaimoana encompasses the full range of Māori seafood: pāua (abalone, Haliotis iris — prized for its firm flesh and iridescent shell), kina (sea urchin, Evechinus chloroticus — eaten raw from the shell), pipi and tuatua (shellfish gathered from sandy beaches), whitebait/īnanga (tiny juvenile fish caught during upstream migration, fried into fritters), karengo (edible seaweed, Pyropia spp. — the NZ nori), mussels (kūtai, Perna canaliculus — the green-lipped mussel unique to NZ), crayfish/kōura (Jasus edwardsii), and various fin fish. The Māori approach varies by species but the principle is universal: minimal intervention, maximum freshness, respect for the oceanʻs gift.

Karamū (Coprosma robusta) berries are bright orange and produce a tart, fruity vinegar when fermented. Fiso makes karamū berry vinegar — a NZ native acid that parallels the vinegar traditions of every other Pacific stop (Filipino coconut vinegar, Hawaiian chili pepper water as a condiment acid). This is NZʻs own acid source, made from a native berry.

Karengo is gathered from intertidal rocks during late winter. It is washed to remove sand, then sun-dried on racks. The dried sheets are dark purple-red, paper-thin, and intensely flavoured. Karengo can be eaten dried (as a snack, similar to nori), rehydrated and added to soups, crumbled over dishes as a seasoning, or sometimes added to the hāngi for aromatic depth. The flavour is deeply marine — more intense than nori, saltier, with a mineral complexity from NZʻs clean waters.

Kumara is the Māori staple starch. Available in red, gold, and orange varieties, New Zealand kumara is particularly sweet and is grown primarily in the semi-tropical regions of the North Island (Northland, Waikato, Bay of Plenty). It is roasted in the hāngi, baked, boiled, or mashed. The Māori developed sophisticated cultivation and storage techniques: rua kumara (underground storage pits) protected the tubers from frost and could preserve them through the winter months. Kumara also holds deep cultural significance as a symbol of fertility and abundance, and its cultivation was governed by specific rituals and tohunga (experts).

Mānuka (Leptospermum scoparium) is NZʻs most commercially valuable native plant. Mānuka honey (with its unique methylglyoxal antibacterial properties) is NZʻs premium food export. But mānuka is also the smoking wood of choice for NZ chefs (like kiawe in Hawaiʻi), and its leaves and bark have been used in Māori rongoā (medicine) for centuries. The smoke, the honey, and the medicine are three expressions of one plant. Mānuka honey is rated by UMF (Unique Mānuka Factor) — the higher the rating, the more potent the antibacterial properties and the more complex the flavour.

Pāua is removed from its shell, the gut is cleaned, and the muscular foot is tenderised by pounding with a meat mallet or stone (traditionally the same kind of pounding action used for poi). Thin slices are pan-fried briefly in butter over high heat — thirty seconds per side maximum. Or minced into fritters. Or added raw to salads (if very fresh). The key is brevity: pāua is naturally tough, and while pounding helps, overcooking turns it to rubber. The flavour is intensely marine, iodine-rich, and unlike any other shellfish.

A potato starter (rēwena bug) is made by mashing cooked potatoes with sugar and water and allowing it to ferment for two to three days until bubbly and active. This starter is mixed with flour to produce a dough that rises slowly, producing a bread with a distinctive sweet-sour flavour, a dense but tender crumb, and a golden crust. Rēwena paraoa is traditionally baked in a camp oven over coals or in a conventional oven. It is a standard accompaniment to the boil-up (pork, puha, and potatoes) and is sold at weekend markets across NZ.

A pit is dug in the earth. River stones (preferably volcanic, heat-retaining) are heated in a large fire until white-hot. The fire remnants are cleared. Wire baskets or traditional flax baskets containing meat (lamb, pork, chicken), seafood (kaimoana), and vegetables (kumara, potato, pumpkin, taro if available, cabbage) are placed on the hot stones. Wet cloths are laid over the baskets to generate steam. The pit is covered with earth to seal the heat. After two to four hours, the hāngi is lifted — the food emerges tender, smoky, and infused with the mineral character of the stones and the earthy, slightly medicinal notes of horopito or kawakawa leaves placed among the food.

This is the entry that defines the NZ food thesis and the Phaidon pitchʻs closing argument. New Zealand food operates on one-to-two steps from source to plate. The fish comes from the sea that morning. The fern frond comes from the forest that day. The seaweed is gathered from the rock at low tide. Nothing is processed. Nothing is disguised. Everything is immediate. This is not rusticity. It is not poverty. It is a philosophy refined over eight hundred years of living at the edge of the habitable world, where every ingredient must justify its presence by being extraordinary in its own right. The philosophy applies to Māori kaimoana, to the flat white (bean-to-cup traceability), to NZ wine (single-vineyard, single-variety), to NZ lamb (grass-to-plate visibility), and to Monique Fisoʻs Hiakai (ingredient-to-table with the raw ingredient presented alongside the finished dish). One-to-two steps. Source to plate. That is NZ food.

Tī kōuka (Cordyline australis, NZ cabbage tree) hearts were an important Māori food. The growing tip and inner core of the stem were cooked in the hāngi — the heat converts the starch to sugar, producing a sweet, slightly fibrous food. Fiso pickles tī kōuka hearts as a sweet garnish. The same genus (Cordyline) as the Hawaiian ti plant (Cordyline fruticosa) used in laulau and lawalu — the Cordyline family runs the entire length of the Pacific migration trail.

Tītī (sooty shearwater, Ardenna grisea, also called muttonbird) is harvested by Ngāi Tahu (South Island Māori) from the Titi Islands near Stewart Island during a strictly regulated April harvest season. The young birds are caught in their burrows, plucked, and preserved in their own fat in pōhā (kelp bags). Tītī is intensely flavoured — rich, oily, savoury-salty, with a distinctive gamey-marine character from the birdsʻ seafood diet. It is one of the most culturally significant Māori foods and is governed by customary harvesting rights (tītī birding rights have been held by specific families for centuries). Fiso features tītī at Hiakai.

Toroi is one of the most important Māori preservation techniques: fresh mussels mixed with the juice of pūhā (sow thistle, Sonchus oleraceus) and allowed to ferment. The pūhā juice acts as both a preservative and a flavouring agent. The result is an intensely flavoured, partially fermented mussel preparation that was stored in pōhā (kelp bags) for later consumption. Toroi connects to the Pacific fermentation thread: Taiwanese millet wine (TW-7), Atayal damamian (TW-3), Hawaiian poi (HI-3). Every Pacific culture uses controlled microbial action to preserve and transform food. Toroi is the NZ expression.

Mamaku (Cyathea medullaris) is the black tree fern — the tallest native tree fern in NZ. The pith of the trunk was eaten by Māori: cooked in the hāngi or roasted, it has a starchy, slightly mucilaginous texture. Fiso uses mamaku in modern preparations (purées, garnishes). The frond tips are pikopiko (NZ-9). The tree itself provides both food and medicine. Mamaku represents the Māori forest-as-larder philosophy: the same tree that provides building material provides food, medicine, and cultural identity.

Young, tightly curled fern fronds are harvested from the bush. They are blanched in boiling water for one to two minutes to remove any bitterness, then served as a vegetable (warm or cold) with butter, salt, or in salads. Some preparations sauté the pikopiko briefly in butter with garlic. The flavour is delicate and easily overwhelmed by strong seasoning.

Red matipo (Myrsine australis) is a NZ native shrub whose berries have a bitter apple taste. Fiso dehydrates them and infuses them into seasonal cocktails and syrups. Red matipo syrup is a Hiakai signature. The ingredient illustrates the depth of the Māori native pantry: there are dozens of native plants with distinct flavour profiles that have no equivalent elsewhere on the trail.

The Māori earth oven — a communal cooking method in which stones are heated in a fire for 2–3 hours, placed in a pit, covered with wire baskets of meat (chicken, pork, lamb) and vegetables (kumara/sweet potato, potato, pumpkin), then buried under sacking and earth for 2–4 hours of steam-roasting — produces food that is uniquely flavoured by steam, smoke, and earth: a subtle, mineral earthiness permeates the quietly yielding, tender meat and sweet root vegetables. Hāngī is always a communal event — prepared by a community of men and women over many hours and consumed by the whole community. It is prepared for tangihanga (funerals), hui (gatherings), and celebrations; the hāngī master's skill in stone selection and heat management is respected knowledge passed between generations.

The centrepiece of the Hawaiian feast — a whole pig cooked in an imu (underground earth oven) lined with hot volcanic stones and wrapped in banana leaves and wet burlap, steam-roasting for 6–8 hours until the flesh is falling-tender, permeated with a subtle smoky-mineral flavour from the stones and leaves — is the most socially charged food in Hawaiian culture: preparing and sharing Kalua Pig is how communities celebrate, mourn, and mark life transitions. The imu technique (lava stones heated in a wood fire for 3–4 hours, placed in a pit, covered with banana leaves, the pig placed on top, wrapped in more leaves, burlap, and earth) produces meat that is uniquely flavoured — neither smoked nor roasted in the conventional sense but something between the two, with a penetrating steam-heat that renders fat completely and produces extraordinary tenderness throughout. Contemporary adaptations use a slow cooker with liquid smoke and Hawaiian sea salt, which approximates the flavour without the community.

The Māori culinary tradition.

The Pacific Island culinary foundation.

Fresh reef fish — yellowfin tuna, wahoo (Acanthocybium solandri), or parrotfish (a reef species that is abundant around Cook Islands lagoons) — is filleted, skinned, and cubed (1–2 cm pieces). The cubes are placed in a bowl and dressed with fresh lime juice. Marination: 15–30 minutes, until the surface turns opaque. The lime juice is drained. Fresh coconut cream (from hand-squeezed grated coconut — the same technique as Fijian lolo, FJ-5) is added. The distinctive Cook Islands additions: freshly grated ginger root (Zingiber officinale, approximately 1 tablespoon per 500g fish), diced tomato, finely sliced onion, diced cucumber, sliced spring onion, a moderate amount of fresh chilli, and salt. The ginger is the marker — it adds a warm, peppery sharpness that distinguishes ika mata from all its corridor neighbours. The dish is served immediately at cool temperature.

Kawakawa leaves are used fresh or dried. Fresh leaves are brewed into tea — the most common traditional use, drunk for digestive complaints, colds, and general wellness. Dried and ground kawakawa is used as a seasoning — it has a warm, peppery heat milder than horopito (NZ-4) but with a distinctive anise-like backnote. Fiso uses kawakawa in syrups, infusions, and as a finishing herb. OCHO Chocolate in Dunedin pairs kawakawa with horopito in their native-spice chocolate bar. The berries (small, orange-yellow, produced on female plants only) are also edible — peppery and aromatic, used sparingly as a garnish.

The kina shell is cracked open with a rock or knife — strike at the mouth (the flat underside). The five strips of roe are visible inside, ranging from bright golden-orange (prime condition, pre-spawning) to pale cream (post-spawning, inferior). The roe is scooped out with a finger or a small shell and eaten immediately. Prime kina roe is creamy, sweet, intensely briny, with a custard-like texture. In restaurants (Monique Fiso's Hiakai served kina panna cotta), the roe is used as a flavouring agent — folded into custard, added to pasta, or served on toast. But the purist method is the one practised by coastal Māori for centuries: crack, scoop, eat.

A pit is dug in coral sand or volcanic soil (depending on the island — Rarotonga is volcanic, the outer atolls are coral). Basalt stones (from volcanic islands) or coral stones (from atolls — these are less effective and crack more) are heated with coconut-husk fuel. Once the stones are white-hot, the fire is raked clear. Food is wrapped in banana leaves or purau (wild hibiscus) leaves — purau is a Cook Islands distinction, producing a faintly floral note in the cooked food. Root vegetables (taro, kumara, breadfruit) are placed on the stones. Proteins (whole pig, whole chicken, whole fish) are wrapped and placed on top. Ika mata parcels (CK-2, raw fish in coconut cream — pre-prepared but warmed in the umu edges) and rukau parcels (taro-leaf-in-coconut-cream, the Cook Islands cognate of palusami/rourou) are placed in the gentlest heat zone. The umu is sealed with banana leaves, mats, and in some islands, a thin layer of sand or earth. Cooking time: 3–6 hours. The opening of the umu kai is a communal event — the food is distributed by the host family.
