The south island usually has a surplus of power, and the north island a deficit.
The distance is several hundred kilometres, and for long distances, DC has less loss than AC.
Also, the equivalent DC voltage will be .707 of the AC voltage, thus savings in insulator costs. Similarly, the undersea cables only need to withstand a lower voltage.
The DC voltage in the cables is + 250KV and -250KV.
The current is re converted to AC in the southern part of the north island.
One of the significant problems, is that one has to convert the signal to almost pure DC, for simple rectified AC has horrendous noise radiation. And Capacitors (the usual solution to that problem) are impractical when you are dealing with Megawatts.
