The constellations are different due to the fact that you're looking completely different parts of the sky. However, some constellations which are directly above the Earth's equatorial regions remain the same.
They see the Northern and Southern constellation stars respectiively.
The Stars on the New Zealand flag represent the Southern Cross Star constellation which is only visible in the Southern Hemisphere, and south of latitude 30 degrees in the Northern hemisphere. The formation actually omits the fifth star in the constellation.

So that the whole sky is covered. In the northern hemisphere, you don't get to see all of the stars in the southern skies and vice versa. If you are observing something that moves from the south to the northern skies then you need to involve someone in the southern hemisphere. Also, South Africa is on more or less the same longitude; similar time difference, so observations at each site will be happening at the same time.
Yes it does; both places are located on the Northern Hemisphere.
No; the sky looks entirely different in the Southern Hemisphere vs. the Northern Hemisphere.
Yes, there are more visible stars in the southern hemisphere than in the northern hemisphere because the southern hemisphere has fewer large cities and less light pollution, which allows for better visibility of stars. Additionally, the southern hemisphere has the center of the Milky Way galaxy, which contains more stars than the outer regions where the northern hemisphere is situated.
The southern hemisphere is the half of Earth that is south of the equator. It includes continents like Australia, Antarctica, most of South America, and parts of Africa. Seasons in the southern hemisphere are opposite to those in the northern hemisphere.
Some northern hemisphere stars can be seen from the southern hemisphere depending on the latitude. For example, Polaris, the North Star, cannot be seen from the southern hemisphere. However, stars like Vega and Capella can be visible from both hemispheres.
They used them to navigate (for instance, the Southern Cross in the Southern Hemisphere or the Northern Star in the Northern Hemisphere) or to build their farming and religious calendars.
Always above the horizon at your latitude. In the northern hemisphere this will be the northern horizon and the reverse for the southern hemisphere.
In the northern hemisphere you want to look for Polaris or the northern star. This star is special as it does not move much, and is always in the north. All of the other stars appear to rotate around it as the earth spins on it's axis. You can find this star by looking for the Big Dipper, take the end two stars opposite the handle and continue the imaginary line further until you get to it, the end of the Little Dipper. In the Southern Hemisphere, look for the Southern Cross.

In the southern hemisphere, stars appear to move from east to west in a clockwise direction due to the Earth's rotation. Polaris, the North Star, is not visible in the southern hemisphere. The Southern Cross and the constellation Crux are prominent in the southern sky and can be used for navigation.
For the most part there is less developed land in the Southern Hemisphere than in the Northern Hemisphere. That means that at night when you can see the stars there is less light pollution, and generally, I believe. less air pollution. Less air pollution means less tiny particles in the air. Particles tend to interfere with the passage of light, so you can't see stars that give off less light. At the same time "Light Pollution" makes the sky seem lighter providing poorer contrast and making weaker stars more difficult to see. In other words, stars are not brighter in the Southern Hemisphere, they're just easier to see.
