The announcement is expected to further stoke opposition to seismic testing and possible oil drilling off the Northland coast. An awareness day is being planned at Ahipara early next month.
Mr Bridges said he encouraged iwi and local authorities to take part in the consultation process, which closes on February 9, 2015. Their feedback would ensure sensitive areas were carefully considered before the tender round was finalised.
Mr Bridges said the block offer was "not about development at any cost" with the Government committed to promoting and managing exploration in a safe and responsible way.
The proposal, which comprises four offshore and three onshore areas, covers about 476,000 sq km. New Zealand's total land area is about 270,000 sq km.
Rueben Taipari Porter, a leading opponent of oil exploration, said he had been disappointed with the last consultation round, which he believed was set up to ensure the Government got its way.
Rather than fight the Government's plans with yet more paperwork, his group was working to raise awareness among those most at risk from oil exploration. He was amazed by how many people were unaware that seismic testing was due to begin within weeks off Northland's west coast.
An awareness day, including music and expert seminars, will be held at Ahipara on December 6.
