Today, she said those comments were made after being asked by media if her Government would authorise a re-entry if there was evidence people could lose their lives.
"And the point I was making was, actually, the families have never asked us to do that. They have simply asked us to commit to investigating and utilising the evidence they have…and that is what we are doing."
Ardern was also quizzed about another aspect of the coalition agreement with NZ First – using a new regional development fund to plant 1 billion trees over 10 years.
National has accused the Government of backtracking on that pledge, because Forestry and Regional Economic Development Minister Shane Jones has said the private sector would plant about half of all trees.
Ardern said the Government had always been clear others would be involved in the 1 billion tree goal.
"Whether or not we are the ones physically out planting the trees, whether or not we are the ones that have forestry service assistance, whether or not there are government subsidies involved in some of those plantings – there is a lot of government involvement, even when the private sector is involved.
"Our commitment is to plant a billion trees. I absolutely accept that people will need to see the proof in the pudding. I absolutely accept that. All I'm asking, four weeks in, is to give us the ability, the time and the space to be able to prove that."
