"We have to ensure that people's actions do not harm other people, that they do not act in a way that will hurt someone that will also not provide any benefit," Wall said.
Wall paid tribute to abortion advocates Dame Margaret Sparrow and Terry Bellamak in her speech.
By a strange twist of fate this particular bill is not a Government bill, despite the idea coming from the Government's abortion law reform programme, which began in 2018 and culminated in a bill making access to abortion easier passing in 2020.
Instead, this particular piece of legislation came from backbench Labour MP Louisa Wall, who picked up the idea as a member's bill after provisions to ban protesting outside abortion clinics fell out of the Government's main abortion law reform bill in 2020 almost by accident.
The Government had included provisions to establish safe areas in its original abortion bill, but they were taken out in a late-night sitting of Parliament.
Act leader David Seymour had two amendments to that bill, which would have removed safe areas. The first amendment did not pass, indicating that safe areas were supported by a majority of MPs.
But supporters of safe areas failed to muster themselves to trigger a counted or "personal" vote on the second amendment, despite the fact they had the numbers to vote it down. Instead, it passed on a voice vote.
As a result, safe areas were effectively removed from the bill. Wall later decided to pick up the cause as a Member's Bill.
In a strange twist of fate, Seymour himself voted in favour of this bill - as did all Act MPs. He alluded to the fact that he had switched votes on safe areas between bills.
"The genesis of this bill I had a little bit to do with Act," Seymour said.
"Act has watched this bill change to the point where it is consistent with the values of free speech, and we can support it," he said.
Seymour said he believed the select committee's changes to the bill brought it to a place where he could vote to it, noting the Attorney-General David Parker now considered the changes to be consistent with the Bill of Rights, whereas the initial version of safe areas had not been.
Seymour said the initial definition of what could be prohibited in a safe area was too broad, prohibiting simple communication. This had been tightened to ban more specific forms of protest, like obstructing people and filming them.
