Mr Baldock said it was a challenging task to give effect to the country's 1840 founding document in the 21st century. "It is perhaps a dangerous minefield that any new and inexperienced political party would venture to campaign on."
Solving racial tension over the past 30 to 40 years had been a difficult journey requiring wise heads from all sides of the political spectrum, he said. "There are no simple answers or campaign slogans that offer real solutions."
Mr Baldock said the legal requirement to consult Maori had brought New Zealanders together more than it divided them. Doing what the Conservative Party was advocating would "stir the country up like crazy".
The irony of the "one law to rule us all" policy was that it would divide the country, he said.
Mr Baldock has not resigned his membership, is still a member of the national board and wants to play a part in the Conservative Party's post-election review process.
Mr Baldock, who championed opposition to anti-smacking legislation by organising the collection of one million signatures, has been a board member since the party was formed three years ago.
He stood as a candidate in Tauranga for the 2011 election and was No3 on the list.
"It was generally accepted that I would stand in Tauranga once again," he said.
Mr Craig responded that the choice of candidate was considered afresh each election: "Although Mr Baldock stood in the electorate in 2011 for the Conservative Party he was required to go through a selection process for the 2014 election.
"As a result of the process and subsequent discussions, it became clear that Mr Baldock was unable to fully support the policy platform of the party."
