Sandboarding is sand surfing on your belly, head-first while you fly to the bottom of the dunes, laughing and smiling all the way. The giant Te Puki Sand Dunes reach up 100 metres, with the longest run nicknamed "Devil's Hook" offering a 350m long metre "surf" down. And it's fast, as some of the slopes exceed 45° (estimated).

The Ruakaka deposit consists of andesine (67%), quartz (25%), iron-rich minerals (4%) and rock fragments (4%). The northern end of Ruakaka Flats is estimated to contain 50 Mt of sand, which would yield, at 60% recovery, 30 Mt of saleable minerals. At the southern end there is probably in excess of 350 Mt of sand.
This diagram illustrates the main steps in the production of steel in New Zealand. Ironsands are taken from the beach at Waikato North Head and reduced to an iron-rich concentrate. This is piped to the Glenbrook steel mill. There it is blended with coal from nearby Huntly and reduced to molten pig iron by smelting.
