The trio visited Macandrew Bay and Bathgate Park Schools as part of an outreach programme for schools that do not have easy access to the Beehive in Wellington.
A mock chamber session, which lasted an hour, gave pupils the chance to learn how Parliament worked.
Politicians were asked largely environment-centred questions, but also about over-population, birthing units, and what Parliament smelled like.
Ten-year-old pupil Margot Latton said her favourite part was when the politicians said funny things to each other during the debate, and she had a very fun morning.
Mr Mallard said the children asked sensible and important questions.
It was good for the children to hear how Parliament worked from different perspectives.
"Having a range of people involved, it means you can do the parliamentary stuff without being political."
