Te Riu a Maui is above and below, it's just that most of it is under water

Te Riu a Maui also known as MU. The coordinates are the beating heart of papatuanuku, earth mother – 'the Moana Heart'.

As it stands, Te Riu a Maui pierces the earth's surface, above and below New Zealand. It's a continent - most of which just happens to be under the sea. 

Te Riu a Maui and Gondwana are physically bound to each other across the Cato Trough, off the coast of Queensland. Spiritually bound to each other from Rangihoua across the Rangihou in Paremata, New South Wales.
