A Traditional Hangi Method for Lake Rotorua’s Finest Catch
The waters of Lake Rotorua have sustained the Te Arawa people for centuries. When you pull a fat rainbow trout from these ancestral waters, you are connecting to a long line of fishermen who came before, who knew that the best way to honour a catch is to cook it with patience and respect for the old ways. This recipe brings the authentic flavours of a traditional hangi into your home kitchen, or better yet, to your backyard fire pit.
In a true hangi, we dig a pit, heat volcanic rocks with manuka fire, and let the earth do the work for hours. The result is meat and vegetables so tender they fall apart, infused with a subtle smokiness that no oven can quite replicate. This method adapts those principles for a whole rainbow trout, using rewana bread in the stuffing and layers of native flavour that will transport you to the shores of Lake Rotorua.
The Best Fish for This Recipe
Rainbow trout from Lake Rotorua are prized for their firm, pink flesh and clean flavour. They take on smoke beautifully and hold their shape during long, slow cooking. These fish thrive in the lake’s geothermal-influenced waters, which gives them a unique character you will not find anywhere else.
If you have never fished these waters, the local guides at Great Lake Fishing Tours know exactly where the big rainbows feed. We have spent years reading the lake, understanding the seasons, and learning where the fish gather. Let them take you to the secret spots.
The Recipe: Hangi Rainbow Trout with Rewana Bread Stuffing
This recipe creates a complete meal in one parcel. The fish steams inside cabbage leaves while the stuffing soaks up all the natural juices. If you can cook this in a proper outdoor hangi pit, you will taste something truly special. If not, your oven will still produce a remarkable dish that brings a taste of Te Arawa tradition to your table.
Ingredients
For the Fish
- 1 whole rainbow trout, cleaned and scaled (about 2 kg serves 4 to 6 people)
- 8 to 10 large cabbage leaves or pikopiko (native fern shoots) if you can find them
- 2 tablespoons manuka olive oil or regular olive oil
- Sea salt and flaky sea salt for finishing
- Juice of 2 lemons
For the Rewana Bread Stuffing
- 2 cups crumbled rewana bread (traditional Maori potato bread), crusts removed. If you cannot find rewana, use a dense sourdough.
- 1 onion, finely diced
- 2 cloves garlic, minced
- 100g butter
- 1 tablespoon manuka honey
- A generous handful of fresh horopito leaves, finely chopped. Horopito is a native pepper leaf with a warm, spicy kick. If unavailable, use a pinch of cayenne and black pepper.
- ¼ cup chopped fresh parsley
- ¼ cup chopped fresh puha or watercress. If you cannot find puha, use extra watercress or spinach.
- Salt to taste
For the Smoky Element
- A handful of manuka wood chips if using an oven or barbecue
- If building a hangi pit, you will need manuka firewood and volcanic rocks
Method
Step 1: Prepare Your Hangi (If Cooking Outdoors)
Dig a pit about half a metre deep and wide enough for your fish parcel. Line the bottom with manuka wood and stack volcanic rocks on top. Light the fire and let it burn for 2 to 3 hours until the rocks are white hot and glowing. The fire should burn down to hot embers. This is the traditional way, and it rewards you with flavour you cannot get anywhere else.
Step 2: Prepare Your Stuffing
Melt the butter in a pan over medium heat. Add the onion and garlic and cook slowly until soft and golden, about 10 minutes. Stir in the manuka honey and let it bubble for a minute. Remove from heat.
In a large bowl, combine the crumbled rewana bread, chopped horopito, parsley, and puha. Pour the onion and butter mixture over the top and mix well. Season with a little salt. The stuffing should be moist but not soggy. Set aside to cool completely.
Step 3: Prepare Your Parcel
If you are using cabbage leaves, blanch them in boiling water for 1 minute to make them flexible. Drain and pat dry. Lay out a large piece of heavy duty tin foil. On top of the foil, create a thick bed of cabbage leaves or pikopiko, overlapping them generously to form a base larger than your fish.
Step 4: Stuff the Fish
Pat the rainbow trout completely dry inside and out with paper towels. This step matters, a dry fish means better texture and flavour. Season the cavity generously with salt.
Pack the rewana bread stuffing tightly inside the cavity. Do not overstuff, as the stuffing will expand slightly as it cooks. If you have extra, form it into small balls and wrap them in separate cabbage leaves to cook alongside the fish.
Rub the outside of the fish with manuka olive oil and season all over with salt. Squeeze lemon juice over the skin and inside the cavity.
Step 5: Wrap the Fish
Lay the stuffed trout on top of the cabbage leaf bed. Fold the leaves up and over the fish to completely enclose it. The leaves protect the fish and keep every drop of moisture inside.
Now wrap the foil tightly around the whole parcel. Fold the edges over several times to create a perfect seal. No steam should escape. This is essential for that moist, tender result.
Step 6: Add Smoke (For Oven or Barbecue Cooking)
If you are not using a hangi pit, you can still get that smoky flavour. Soak a handful of manuka wood chips in water for 30 minutes. If using a barbecue, scatter the wet chips directly over the coals just before you place the fish parcel on the grill. If using an oven, place the wet chips in a small metal tray or foil packet with holes poked in it, and put it directly on the oven rack alongside the fish. The chips will smoulder and release smoke throughout the cooking time.
Step 7: Cook the Fish
For a Hangi Pit:
When your rocks are white hot and the fire has burned down, carefully place the foil parcel directly onto the rocks. Cover immediately with wet sacks or leaves, then shovel earth over the top to seal the heat in completely. Leave for 2 to 3 hours. The slow, steady heat will produce impossibly tender fish that flakes at the touch of a fork.
For a Barbecue:
Preheat your barbecue to medium heat, around 160 degrees Celsius. Place the foil parcel on the grill away from direct heat if possible. Close the lid and cook for 45 to 60 minutes.
For the Oven:
Preheat your oven to 160 degrees Celsius. Place the foil parcel on a baking tray and cook for 50 to 60 minutes.
The fish is ready when it is opaque and flakes easily. The stuffing should be steaming hot and fragrant, having absorbed all the wonderful juices from the trout.
Step 8: Serve with Pride
This is a moment to share. Carefully open the foil at the table so everyone can breathe in the steam. It will smell of manuka, of butter and herbs, of the lake itself. Lift the whole parcel onto a large platter and peel back the cabbage leaves to reveal the glistening fish, perfectly cooked and glistening.
Your guests can pull the flesh away in large flakes, scooping up the rewana stuffing alongside. A final sprinkle of flaky sea salt and a squeeze of fresh lemon is all it needs. Serve with simple boiled potatoes or kumara to complete the meal, letting the fish remain the star.
A Note on Native Ingredients
Horopito and puha are traditional Maori ingredients that deserve a place in more kitchens. Horopito grows as an understory shrub in our native forests, and its leaves carry a peppery heat that builds slowly on the tongue. Puha, or sow thistle, grows wild throughout the country and has a pleasant bitterness that cuts through rich food. Both are worth seeking out at specialty grocers or learning to forage responsibly with someone who knows the land.
Your Catch Awaits
This is kai prepared the way it was meant to be, with patience, with fire, and with respect for the whenua. The best part of this meal is catching the fish yourself, standing in the same waters your ancestors fished, feeling the same tug on the line that fishermen have felt for generations.
Let us help you make that happen. Book a tour with Great Lake Fishing Tours and we will put you onto the finest rainbow trout in Lake Rotorua. Our guides know these waters intimately, and they will share their knowledge while you create memories that last a lifetime. Then you can bring your catch home and cook it the Te Arawa way, connecting your own story to the long history of this place.
