New Zealand Water, across the board is renowned for its purity.
Antipodes is amongst the most pure.
Antipodes comes to the surface from a deep aquifer and is bottled at source in Whakatane, Bay of Plenty, New Zealand.
To quote the rather dry but authoritative Geohydrological Assessment of the BOPRC Technical Publication No.2, 1998:

"The groundwater of the Aquifer is of very high quality.
It has been recognised as the deepest, highest quality groundwater in New Zealand".

And yep, you guessed it; this source is now less boringly known as Antipodes.
