Do they add the leap second at the same moment in time throughout the world,
or are the clocks here in NZ running 13 hours and 1 second ahead of those in
the UK for half of Jan 1st?

It's added at the end of the last day of a month, UTC.

That makes if 4PM local time in California, a convenient time for watching
toys.

Leap seconds at the end of June could happen at inconvenient local times.
