Not actually the first PM
The Herald reports:
Ponsonby Road was lit up in every colour of the rainbow for the Pride Parade.
More than 3500 people took part in the annual parade – including Prime Minister Jacinda Ardern – while tens of thousands of people lined the street to watch the action.
Ardern launched the parade by cutting the last of several rainbow ribbons shortly before 7.30pm.
She became the first Prime Minister to walk in the event, marching alongside the Labour Party’s red caravan.
She’s not the first PM – not by 19 years.
Jenny Shipley attended the Hero Parade as PM in 1999. The Pride Parade is basically the same event, under a different name.
