Eyre River (New Zealand)
The Eyre River is a river in the Canterbury region of New Zealand. It arises in the Puketeraki Range and flows south-east into the Waimakariri River near Christchurch International Airport. The connection with the Waimakariri is via a diversion channel running south-west, replacing the Eyre's original easterly flow. The river is named after Edward John Eyre, the Lieutenant-Governor of New Munster from 1848 to 1853. The river rarely carries surface water, due to the unreliability of the easterly rains which feed it.
