Oil Free Wellington spokeswoman Jessie Dennis said deep sea drilling threatened coasts and marine life, contributed to climate change and was "simply not worth the risk".
"The seismic survey blasts can have an impact on marine mammals exposed to these sounds such as disorientation which could lead to stranding."
"We know that we need to keep 80 of known fossil fuel reserves unburnt to have a chance of keeping below two degrees of warming. Instead of locking ourselves into a fossil fuel intensive future, New Zealand should transition towards a sustainable and just society."
A march to oppose the seismic surveying will to take place at midday tomorrow, starting from Midland Park.
Labour Leader David Cunliffe yesterday announced that a Labour-led government would change laws to strengthen environmental protections around deep sea oil exploration but would work with existing explorers to allow them to meet the new standards.
