MetService, New Zealand's National Meteorological Service, has had a $1.7 million refresh.
Last week a beta version of the new site went live, and MetService is encouraging feedback over the next few months.
The changes include improved Marine, Rural and Mountain and Park sections as well as an interactive map of severe weather watches and warnings.
One of the main changes is an increase in clarity of Severe Weather Warnings on the site.
It features a new interactive map showing watches and warnings and the introduction of a two-tier land-based warning system.
