Protected as one of New Zealand’s key birthplaces, welcome to Ōtuataua Stonefields Historic Reserve. This area is not just a park. It is a window into the lives of early Māori. It offers a glimpse into their innovative gardening techniques. Imagine stepping back in time. Picture the landscape as it once was. It was a thriving hub of activity.
The story of Ōtuataua Stonefields begins long before European settlement. Around the 15th century, new Polynesian arrivals began planting gardens here. These gardens spread across thousands of hectares. The main crop was kūmara or sweet potato. These early New Zealanders transformed the volcanic landscape into fertile gardens. They developed sophisticated methods for cultivating crops.
Two hundred years ago, there were about 8000 hectares of volcanic stonefields in Auckland. Today, the 100-hectare reserve of Ōtuataua is all that remains. It was established in 2001. The reserve protects this important part of the archaeological record. It is one of the last places to see large-scale remains. Here we can still appreciate how people once lived and worked. They thrived in the volcanic areas of Auckland.
One of the most remarkable features of Ōtuataua is the mound gardens. Māori people built these gardens as special plots. They used the stones’ heat-absorbing properties. This helped warm the earth. It also retained moisture. These mounds often contained specially modified soil. This included added organic matter and ground shell. This ingenious technique extended the growing season by about a month.
Walking through Ōtuataua, you will notice low hills and gullies. The gully floors are free of stones. The stones have been stacked on top of the hillocks. This left the gully floors clear for cultivation. It is said that nearly every stone here has been moved by human hands.
Another interesting feature is the pā. This is a hillfort or defended settlement. It used the volcanic cone. Auckland has many volcanic cones. All were used and settled by Māori throughout history. Unfortunately, this particular cone was quarried for scoria. This happened before the site became a reserve. This resulted in the loss of a large part of the pā. However, you can still make out the terraces on the southern side. These level areas were cut into the lower slopes. Māori lived on these terraces.
Also of interest is the site referred to as ‘The Big House’. Here you can see a rectangular outline of stone. This is believed to be the foundation of a large house or structure. Nearby are several shell middens. These middens indicate that meals were eaten here. Perhaps it was a communal place. A place to share food while working in the gardens.
All over Ōtuataua, shell middens can be found. This is not surprising given the proximity to the coast. Fishing, shellfish gathering and horticulture were mainstays. They were the mainstays of the local economy.
Unlike in Polynesia, kūmara could not be left in the ground over winter in New Zealand. The early settlers found they needed to harvest the kūmara and store it. At Ōtuataua, you will see shallow depressions in the ground. These are roughly rectangular in shape. They are usually found on slopes or ridges. These are the remains of storage pits for kūmara. Originally, these pits would have had timber walls and thatched roofs. The storage pits here are outside of the defended pā. This suggests that the people felt secure here. They felt safe on the edge of the Manukau Harbour.
Ōtuataua Stonefields Historic Reserve is more than just an archaeological site. It is a testament to the ingenuity and resilience of early Māori. They transformed a volcanic landscape into a thriving community. This remarkable place connects us to the past.
