New Zealand authorities blast James Blunt and Baby Shark at vaccine mandate protesters

Authorities in New Zealand upped the ante on Sunday as they tried to disperse protesters from outside the country's parliament.

After Barry Manilow's greatest hits on a loop failed to dislodge the anti-vaccine mandate demonstration, which has been sat outside for almost a week, they turned to a song that strikes fear into the hearts of parents around the world: Baby Shark (Doo Doo Doo).

They even joined a sing-along to James Blunt's 2005 hit, You're Beautiful.

The British singer cheekily tweeted NZ Police on Saturday about the Manilow plan: "Give me a shout if this doesn't work."

As of Monday however, protesters have not been moved, with hundreds still remaining outside parliament.
