TIKI has implemented sustainable winegrowing methods, particularly in Waipara, and Marlborough where merino lambs graze out weeds under the vines in the winter, reducing the need for spray herbicide and mower use.
To help increase soil health a ground drench containing liquid seaweed, molasses and beneficial bacteria and fungi is also applied. Some conventional sprays have been replaced by organic options such as seaweed sprays that are BioGro-certified
TIKI maximise recycling opportunities wherever possible and use the Ag Recovery process for all chemical containers. All old vineyard posts are either sold or given to local farmers who in turn use them for fence posts
In its setting at the north-eastern tip of New Zealand's South Island 40 degrees south of the equator, Marlborough lies parallel with some of the northern hemisphere's major winegrowing regions. As the country's largest grapegrowing and winemaking region, it produces close to 75 per cent of wine exports.
Its Wairau and Awatere Valleys are sheltered from the worst of New Zealand's maritime weather by hills to the north and south and its main town Blenheim is a regular contender for the country's highest annual sunshine hours.
Marlborough's legendary status around the globe for sauvignon blanc sparked TIKI's desire to invest in the Upper Wairau Valley. Three vineyards, River Terrace, Te Puki Iti (The Little Hill) and Rewa, are all unique sites with their own distinctive characteristics. Soils are a range of stony silt loams with the upper terraces made up of angular stones (glacial deposits) and the lower terraces of rounded stones (river deposits), reflecting their geological origins.
In addition to sauvignon blanc, pinot gris and pinot noir are also planted.
A 40-minute drive north of Christchurch, Waipara is the fastest-growing wine region in New Zealand, with around 80 vineyards covering more than 1200 hectares.
The Teviotdale hills protect against cool easterly winds but leave the area open to warming north-west winds. In combination with long hot autumns, the terroir contributes to the production of regional specialities, rich, spicy pinot noirs and rieslings. Varieties of note include pinot gris, chardonnay and sauvignon blanc.
Soils in the gently sloping Waiata Vineyard range from stony shingle river deposits through to heavy clays. This variation permits a range of growing techniques which allows viticulturists and winemakers to work together in the vineyard.
Key varieties grown are sauvignon blanc, pinot gris and pinot noir.
New Zealand's highest, and the world's most southerly, wine region, spectacular Central Otago sits at latitude 45º south, ringed by mountains and interlaced with lakes and deep river gorges.
The inland mountainous location provides a semi-continental climate with very cold winters, hot summers, cool night temperatures and very low rainfall. This unique climate, combined with the mainly glacially derived soils with rich deposits of mica and schist, is ideally suited to pinot noir (more than 80 per cent of the total plantings).
The main variety grown is pinot noir.
