Moncks Bay lies on the main road that runs between the suburbs of Recliffs and Sumner in the Avon Heathcote Estuary.
The Clouds above the Estuary are the Nor’west arch or Canterbury Arch, a weather pattern particular to the east coast on New Zealand’s south island and is caused by weather systems moving over the southern alps.
