The education minister says she has already given Labour plenty of opportunities to see a proposed bill that aims to ban social media for under-16s, despite a Labour MP claiming he is the only one allowed to see it.

Labour's science, technology and innovation spokesperson Reuben Davidson told media on Tuesday that he had a chance to see the bill while in the Erica Stanford's office, but was not allowed to take a copy of his own to share with the wider Labour caucus.

The legislation has been on hold since May and Stanford, the minister responsible, said she had "really good" engagements with Davidson and had given him a number of opportunities to read and ask questions about the bill.

She said there were "legal reasons" she could not give Davidson a copy of the bill.

However, Stanford said her and Davidson had set up a briefing where other Labour MPs could get more information on the bill this week.

"I've also said I'm happy to show more of your colleagues, which he asked for last week, and we've now set up a meeting, so they can all come on Thursday and see the bill."

Davidson told media on Tuesday morning that not being able to share the bill with colleagues made it "very difficult" for Labour to make any decision on it.

"I think it's unusual to ask someone to make a decision if they don't have the thing they're being asked to make a decision about in front of them," he said earlier on Tuesday.

The education minister said she had told Davidson and another colleague they were welcome to ask for changes or provide suggestions about the bill, but had not yet received any feedback.

"I have said to him, I expect there to be many changes at Select Committee because we'll have a full process. We expect lots of people to have a say on this.

"But I've played this with a very straight bat and I've offered multiple briefings, I've been really open and said to him 'as many people as you want to see the bill, we'll accommodate that'." she said.

Stanford said her meetings with Labour so far had been "really good".

"Reuben's a good guy; he gets it.

"Our communications so far have been productive, we've been open [and] I've offered many briefings."

Davidson said he first saw a copy of the bill some time last month and had asked for a copy of the bill at follow-up meetings.

He would not comment on the specifics of the bill: "Those are questions you could take to the minister," he said.

"Once our full caucus has been able to see the bill in its entirety, then we'll be able to reach a position on whether we support the bill and the specific details or components of the bill."

Davidson denied Labour was "stalling" the process.

"It's very hard to claim that someone is stalling or that a caucus is stalling on making a decision when they haven't been able to see the bill that they're being asked to make a decision about..

"We've said the whole way through that this issue is too important to play politics."

Asked what platforms would be banned under the legislation, Davidson, again, said questions should be directed to Stanford. However, he said no VPN ban was in the proposed legislation.

Labour Leader Chris Hipkins said if the government wanted Labour's support for the bill it would need to engage more "fulsomely".

Asked again later on Tuesday, Hipkins said his understanding was that Stanford's "current position" was that she was "not negotiating".

"That basically it's you can read the bill and then you have to agree to vote for it, but I'm not making any changes to it... my understanding is that that's what she's indicated to Reuben.

"She said that she'd consider changes through a select committee process, but there would be no negotiation up to that point, so it's not really negotiation, is it? She's basically asking us to write her a blank cheque," Hipkins said.

Asked if she had the support to get the bill over the line, Stanford declined to answer. She said she did not want to "presuppose" what other parties thought about the legislation before it was given to Cabinet and put through Select Committee.
