Portland Island (New Zealand)
|Native name: Waikawa|
|Location||Hawke's Bay region|
|Area||1.4–3.0 km2 (0.54–1.16 sq mi)|
|Length||3.26 km (2.026 mi)|
|Width||0.65 - 0.98 km (-0.205 mi)|
|Highest elevation||106 m (348 ft)|
The area of the island fluctuates rapidly between high and low tides due to a shelf of rocks surrounding the east, north and west coast of the island. During low tide the area of the island can grow up to 3 km², while during high tide it shrinks down to only 1.4 km². This makes access by boat to the island rather difficult, despite it being only a kilometer offshore.
