As well as this, Ardern said the previous National Government had left an even longer gap when considering the bright-line test.
"Obviously the last Government when they sought advice ... and eventually put in place the bright-line test, they received a report, they considered it for four months. We're not suggesting we would do that".
"Maybe one of the differences here is whether or not the scaremongering was occurring during that four month period or not".

"It's not unusual at all for a Government to receive a working group's opinion to take some time to consider it.
"Ultimately ... I don't think we should shy away from hearing people and listening to people's views".
