I happen to know from one the most reliable sources, aka Department of
Conservation, that it is absolutely essential to cut off the trunk below
the lowest needle. Otherwise the tree will coppice, you have problem
times 3, and the mighty ire of DoC on your head. In practice you will
need to move away the top layer of fluff (fallen needles, leaves etc)
from around the trunk to get low enough. After that we also chamfered
the stump, just to be sure.
Yes you can reliably kill those pesty pines but you'll have to
effectively cut below ground level...
