    Climbing

    Kura Tāwhiti (Castle Hill) is an extremely popular place for climbing and bouldering. There are a large number of bolted climbs within the reserve.

    Ngāi Tahu wish to encourage respect for their association with Kura Tāwhiti. A rock-climbing code is in place, and rock climbers are asked to be aware that to Ngāi Tahu, climbing the outcrops denigrates their tapu status.

    About this place

    Nature and conservation

    Landforms 

    Sculptures in stone

    The geology of the rocks at Kura Tāwhiti is tertiary limestone, mudstone, sandstone and tuffs. Limestone is formed from layers of organic sediment, deposited in deep oceans far from land. The layers are compressed into soft, soluble rock.

    The area was once under a large, shallow inland sea that began to infill some 30 million years ago. Pressure over time caused extensive uplift and folding and faulting of the Torlesse and Craigieburn Ranges.

    Thrust up from their origin, the limestone rock was eroded by water into these distinctive sculptured landforms, called a karst landscape.

    Plants

    Kura Tāwhiti is a refuge for hidden treasures - some of the rarest and most endangered plants in Canterbury. Once covered in tōtara and tall shrubs, the area was cleared 600 years ago by fire and has been grazed for almost 150 years. Tussock and pasture are now the norm, with one lone, surviving tōtara nearby.

    Castle Hill buttercup

    Thanks to the work of Dr Lance McCaskill in the early 1950s, this habitat is the site of the first reserve in New Zealand established specifically to protect a plant - the Castle Hill buttercup (Ranunculus paucifolius). Gazetted as a 'Reserve for the Protection of Flora and Fauna' in 1954, it was named Lance McCaskill Nature Reserve in 1987 when DOC was founded in recognition of the work that Lance did for the buttercup. 

    With just 67 plants in existence, the Castle Hill buttercup requires very specific conditions for its survival. It is only found within the 6 ha reserve (a naturally rare ecosystem of gently sloping limestone debris) which was recently re-fenced to protect the plant from being consumed by hares. Other factors that have led to the buttercup’s dwindling numbers include being crowded out by invasive weeds, trampled by livestock and stolen by collectors.  

    The Lance McCaskill Nature Reserve has important scientific value as the longest running plant-monitoring project in New Zealand, and has also protected the Castle Hill forget-me-not (Myosotis colensoi).

    The Castle Hill Basin is also home to two other very rare plants that prefer to live in limestone landscapes. These are limestone wheatgrass (Australopyrum calcis subspecies obtatum) and a tiny 3 cm high sedge (Carex inopinata).

    History and culture

    Tōpuni - a symbolic cloak of protection

    This area has special significance to Ngāi Tahu, with ties that stretch unbroken from distant ancestors to present generations.

    Kura Tāwhiti literally means “the treasure from a distant land”, referring to the kumara that was once cultivated in this region. Kura Tāwhiti was claimed by the Ngāi Tahu ancestor Tane Tiki, son of celebrated chief Tuahuriri. The nearby mountains were famed for kakapo, and Tane Tiki wanted their soft skins and glowing green feathers for clothing to be worn by his daughter Hine Mihi.

    Such stories link Ngāi Tahu to the landscape. The traditional knowledge of trails, rock shelters and rock drawings, and places for gathering kai (food) in the area known as Kura Tāwhiti form an integral part of past and present tribal identity.

    Kura Tāwhiti has Tōpuni status, which is a legal recognition of the site’s importance to the Ngāi Tahu tribe. The term comes from the traditional custom of chiefs extending power and authority over areas or people by placing a cloak over them.

    The existing status of the land as a conservation area is unchanged, but Tōpuni status ensures that Ngai Tahu values are recognised, acknowledged and respected and Ngai Tahu take an active role in management. It recognises Ngāi Tahu mana whenua and rangatiratanga and symbolises the tribe’s commitment to conservation.

    Getting there

    Bounded by the high mountains of the Torlesse Range to the east and the Craigieburn Range to the west, the limestone tors of Kura Tāwhiti Conservation Area dominate the Waimakariri Basin, Canterbury.

    From Christchurch take SH73 towards the West Coast. Kura Tāwhiti is beside the highway in the Waimakariri Basin, about 80 minutes from Christchurch.
