LANDLOCKED: There's no way out of Manukau Harbour according to Google Maps.

A Google map error has transformed Manukau Harbour into New Zealand's second largest lake.

The harbour, the country's second largest, sits on the south west coast of Auckland, with Auckland Airport located on the rim.

The harbour's entry is squeezed between Huia and Wattle Bay, but if you're referring to Google Maps then it's not water between those two areas, but land instead.

GOOGLE PICTURE PERFECT: Manukau Harbour appears correctly in Google's satellite view.

While the mistake is apparent in the standard Google Maps, the correct image appears on Google Maps' satellite version.

The mistake is the latest in a long run of recent gaffes by internet giants when it comes to maps.

Apple's new maps unveiled in September placed Timaru Airport in Christchurch and Dunedin Airport 30km from where it is actually located.

Elsewhere in the world it turned an entire city into an ocean, a farm became an airport and highways led to the the middle of nowhere.
