Jurassic forest of ancient kahikatea trees in ‘Turney Bush’ The former farm site is now an important reserve of mature kahikatea trees that once were dominant in the Waikato. Turney Bush kahikatea trees are massive; estimated to be over 300 years old. Their extraordinary root system, designed for swamp life, is exposed. The large roots are buttressed, gnarly foundations for a life where water is a constant in a swamp forest.

Fern birds flitting at your feet as you silently listen to the sounds of the bush and forest

Look and observe the margins of the predator proof fence for plantings designed to build a buffer between the sanctuary and the farmland. The forest margins are dense with flourishing mapou, round leaved native coprosma and hahoe to create shade and protect the reserve from the wind. Seedlings are quickly re-establishing themselves in the bush and forest. Look down for the bursts of green hinting at self-established rejuvenation.

The pest fence helps to block wind and provide shade, acting like a buffer for the small isolated stand. The forest margins were planted up with hardy natives like māpou, round-leaf coprosma and māhoe to quickly seal the edge and create a more natural humid and shady forest interior. Back in the 1980s, the council planted a stand of dense tōtara and kahikatea off the ridge to the north of the big stand, and later planted a nurse crop linking the two to allow the kahikatea forest to double in size. The removal of rabbits and hares from inside the pest fence means seedlings can self-establish.


Explore the world of peat lakes, natural wetlands and where ancient kahikatea trees ensure their roots are not saturated with exposed roots trailing the undergrowth. Play eels and ladders, mudfish scrabble and guess “whose poop” with tips and boxes full of information sheets to assist the hunt for facts and fun outdoors.

  • Open two doors into a pest-free sanctuary.
  • Learn from hands-on activities on the Rotopiko Discovery Trail.
  • Look for Fred the Thread – the world’s skinniest caterpillar.
  • See a Coca Cola coloured peat lake and ancient kahikatea trees standing on their tippy toes.
