Thousands of anti-deep sea oil drilling protesters made their message heard at a protest in central Auckland this afternoon.
An estimated 3000 people played drums, chanted slogans and held placards during the protest.
Greenpeace climate and energy spokesperson Steve Abel said deep sea drilling risks a catastrophic oil spill that could irreparably damage New Zealand's oceans, coasts, economy and way of life.
Mr Abel said the drums were a symbol of the harmful seismic blasts that were created by ships prospecting for oil in New Zealand.
The blasts, which can be heard from over 100km away, are the first step of oil exploration, and involve a ship firing off repeated seismic booms from underwater airguns every few seconds, day and night.
