Asked if the RSE scheme was akin to "modern-day slavery", Wood said groups had come together to ensure workers had better conditions and that there a suitable standard in place.
Asked if he could guarantee if any of the 3000 would not face exploitation, Wood said that's what they were working on.
Measures that included a roving workplace representative were under discussion and that there was a "robust regime", Wood said.
Wood rejected allegations that exploitation of RSE workers wouldn't have been allowed to continue if the workers were white and said funds had been invested to stamp out migrant worker exploitation.
Asked about a journalist's contention the Christchurch mosque shooter wasn't a "terrorist", Ardern said it was a "misguided publicity stunt".
The Prime Minister wouldn't directly address whether it was appropriate for her Ministers to appear with the journalist.
Crime wave help
In response to the recent spate of ram raids and smash and grabs and what is being done to help, Ardern said 500 businesses were eligible under a retail security fund, but only five had received help so far. Ardern said she wanted to see that ramp up.
Ardern said she wasn't comfortable with the speed at which businesses were getting help and wanted it to happen faster.
A bill on maternal birth injuries is before the House and Ardern said the law was a significant change and was part of a wider body of work to ensure ACC was covering all New Zealanders' needs.
"As a Government, we want to make sure the early stages of a child's life and a family's life together is the best it possibly can be," she said.

She ran a shortened Labour caucus meeting this morning to make room for Cabinet, which was rescheduled after the Government made yesterday a one-off public holiday in honour of the Queen.
Ardern has had favourable coverage for several weeks now, with most opinion polls showing a very tight contest between the left bloc and right bloc.
The Herald's Mood of the Boardroom survey of top CEOs on Friday, which has previously rated Ardern very highly, ranked her only the 12th most effective minister. Greens co-leader James Shaw was rated the best performing minister.
When asked about the Mood of Boardroom results, she said she would reflect on other signs on how the economy was performing such record-low unemployment and GDP growth.
"I would have thought those are all signs that [business] should take heart in. We know it has been a tough winter.
"We are rebuilding and working very hard to strengthen the economy, but the signs are there and, of course, we are looking forward with optimism to the summer ahead of us."
Another political opinion poll is due out tonight, the 1 News Kantar poll, which in August had National on 48 per cent and Labour on 44 per cent.
National and Act would have been able to form a Government, had the results been translated into an election result.
