Jacinda Ardern sits down with Christiane Amanpour on CNN

Prime Minister Jacinda Ardern has sat down with CNN, discussing topics like New Zealand's rate of domestic violence, running the country while parenting baby Neve and world maps without New Zealand.

Speaking to hard-hitting journalist Christiane Amanpour, Ms Ardern refused to sugar-coat New Zealand's high rate of domestic violence and admitted how poor our abuse and reporting rates are.

"For some time we have had horrific rates of domestic violence, intimate partner violence, our reporting rate has been as low as nine percent," she told Ms Amanpour on Wednesday morning (NZ time).

Ms Ardern opened up about the recent revelation wealthy doomsday preppers are buying up land in New Zealand, saying she only wanted investment that would benefit the country.

"We are a country that welcomes overseas investment into our productive economy, we want it to be of genuine benefit to New Zealand," she said.

"We want to grow jobs off the back of that investment. We've taken a particular view when it comes to simply purchasing residential housing, and that’s simply because we have a housing crisis."

"We've said no to offshore residential purchases where someone has no long term interest in residing in New Zealand and making a home and a base there."

The Prime Minister also spoke about how she integrated three-month-old baby Neve into her role, admitting she wants to normalise the juggle for others.

"What I consistently acknowledge is that I have assistants who help Clarke [Gayford] with the ability to juggle his career and be our primary caregiver," she said.

"What has struck me is the number of men and women who have said 'we do the same thing'. There's a lot of discussion... we need to normalize that too."

As well as politics, Ms Ardern also addressed an issue she has publically fronted a campaign on - New Zealand's place in the world and especially maps.

"We're not actually on every map that's out there," she said, as Ms Amanpour exclaimed in surprise.

"It's actually a real problem, we've had a campaign around it, there are maps where we are missing."
