Our working relationships

We strive for a close working relationship with our customers, production specialists and breeders, through regular visual and verbal reports, and regular interactive visits.

Ariki Seed currently produces open field crops with contract growers and protected crops on our own homefarms. We hold long-term strategic alliances with growers and specialised contractors, enabling us to cater for customers of all sizes.

The local climate

Ariki Seed's production areas are Canterbury (latitude 44.2) and Blenheim (latitude 42.2).

These areas have a variety of micro-climates which are southern equivalents of Northern Italy, Southern and Northern France, and the North West of USA.

New Zealand has an island climate which is ideal for seed growth; on the South Island, the Southern Alps contribute to rain shadow in Canterbury and Blenheim. The proximity of the ocean with its current from the southern ocean levels the peak summer temperatures, keeping summer temperatures under 30° C.

This east-side current is also responsible for strong temperature fluctuations between day and night. Winters are mild and generally dry. The average monthly rain fall in our production areas is 50 mm per month.
