She said after 13 sessions they were still hearing something new at every stop of the tour.
"It has been a very valuable experience.
"The richness of the information we have learned through this experience we can't replicate or supplicate through other methods."
The bill itself has not been drafted yet and Smith said that was to get as much community feedback first as they could.
So far the bill has received about 4000 submissions, she said.
She said the Te Arawa perspective had been particularly important.
"We can't do our job well as public servants without having that perspective.
"We really want to thank Te Arawa for giving us the opportunity."
Heather Sayer, a member of Forest & Bird, said she wanted to become better informed and educated about the bill.
"I've looked at the website and it's something Forest & Bird strongly support.
"As a 75-year-old I'm very concerned about the legacy we're going to leave."
Geoff Ogilvie said he had come along because he's a "greenie".
"I'm invested in what my grandkids may or may not have in the future."
He said he was feeling pessimistic about the impact he could have on the bill but was optimistic that we would become extinct.
"Everything that breathes oxygen will be extinct in the near term because of what we're doing to the environment."
