"Going to the beach on a good summer's day is part of our national psyche. Generations of Kiwis have spent their summers enjoying themselves on some of the finest beaches in the world."
But he urged Kiwis not to get complacent and assume our beaches will be around forever.
"Our beaches face several threats which are being accelerated through human activity such as beachfront development and the construction of sea walls. Some beaches are already under enormous pressure and are at risk of disappearing.
"Understanding and working with natural processes, rather than fighting them, is the most effective way for maintaining our coastlines and beaches. For example, many degraded beaches can recover if coastal ecosystems — particularly sandy foredunes — are in a healthy, functioning state.
"Restoring our beaches and coastlines needn't cost the earth. If anything, it's an investment. But it requires a change in thinking on how we our beaches and indeed contribute positively to the whole coastal ecosystem."
Conducted by Horizon Research, 1775 people aged over 18 were surveyed.
People were also asked about erosion and almost two-thirds of Kiwis believed beach erosion was worse than it was 20 years ago, and most were worried that some New Zealand beaches might vanish forever.
