New moon is the same side of the moon that you can see during a full moon. Because of the way the moon rotates around the earth the same side of the moon is always pointed towards earth during all phases.
The dark side is actually known as the far side of the moon and is permanently turned away from the earth. It was not seen by humans until the Apollo missions in the 1960s.

Some good replies there folks - thanks
As for the crater issue wouldnt the near side have less because the earth obscures it somewhat from anything impacting directly into it? It could be hit all over the nearside from angles but the farside is fullty exposed.

While the whole of the moon sees sun at some point in its cycle, the earth only ever sees one side of the moon.
So while there isn't actually a 'dark' side, there is a side that we never see from earth.
Most of the large craters on the Moon formed more than 3.8 billion years ago. These were partly filled in by magma that flowed on the surface before the Moon cooled and its geological activity died down. But a number of craters also seem to have been filled in from below.
Researchers believe material from the mantle also rose up in craters, since these are sites where impacts had thinned the Moon's crust. The new Kaguya measurements reveal some craters on the far side that seem to have been filled only with mantle. These craters have higher-than-normal gravity at the centre, surrounded by a thick ring of low gravity that closely matches the original low elevation of the crater.
he Moon's two halves also show other striking differences. NASA's Lunar Prospector, which operated in the late 1990s, found that radioactive elements seem to be concentrated on the near side. The far side also shows less evidence of past volcanic activity.
