From the encyclopedia — geography, climate & geology

Topography & Geography

Geographical Isolation

  • Located in the South Pacific Ocean
  • Distance from nearest land:
    • 1,900 km south-east of Australia
    • 5,000 km north of Antarctica
    • 9,000 km west of Chile
  • NZ's North Island lies on the same latitude as Tasmania

Latitude and Topography

  • Spans 36°–46°S, contributing to climate variation
  • South Island: mostly cool climate
  • North Island: lower latitudes lead to moderate climates (e.g., Auckland and Gisborne)
  • Cook Strait divides North and South Islands
  • North–South city order: Auckland → Wellington → Christchurch → Dunedin (Central Otago)

Vineyard Locations

  • Predominantly on the east of the islands
  • Southern Alps run the length of the South Island, protecting vineyards from excessive rains and prevailing winds from the Tasman Sea (west of NZ)
    • Rainclouds moving eastward from Tasman Sea deposit all moisture high in the mountains → rain shadow effect
  • Marlborough: average of around 650 mm of rainfall per year

Climate & Weather

  • Predominantly maritime climate.
  • Exception: Central Otago — semi-continental climate, sheltered from ocean influence by surrounding mountains (the only region with a truly continental climate in NZ).
