Hemp is Cannabis, so both industrial hemp (iHemp) and marijuana are from the same family, just different varieties.
In New Zealand cannabis is illegal, except iHemp which can be grown legally if you have a current licence issued by Ministry of Health.
iHemp is hemp with a THC content less than 0.35%. Nearly all countries in the world allow industrial hemp and a growing number of countries allow medicinal cannabis and recreational cannabis with higher THC contents.
Hemp is a herbaceous annual plant that produces a nut and is related to hops, it produces leaf, roots, seed and the stems are split into fibre and hurd/shiv.
It can grow to maturity in 90-120 days and produces a seed, fibre or dual (both) crop. It requires little if any pesticides, fungicides and herbicides and can actually clean and condition the soil.
The hemp plant is Cannabis Sativa, belonging to the family Cannabaceae of the nettle order (Urticales)
There are many varieties depending on use and are mainly dioecious (distinct male and female plants) but can be monoecious (male and female on the same plant)
In New Zealand hemp products can only be made from industrial hemp (iHemp) and under our regulations anybody is permitted to possess, use and trade in hemp products and stalks of industrial hemp as long as those stalks are without leaves.
Therefore currently you need a licence to work with hemp seeds, but not the stems or any product derived from the seed. Derived products made from iHemp are legal as they have no THC in them and are no longer part of a viable plant. So at that point hemp products do not need to be controlled as a drug.

“If all fossil fuels and their derivatives (coal, oil, natural gas, synthetic fibres and petro-chemicals) as well as the deforestation of trees for paper and agriculture (e.g Brazilian and Indonesian rain forests), are banned from use in order to save the planet, preserve the ozone layer and reverse the greenhouse effect with its global warming trend; then there is only one known renewable natural resource able to provide all of the following goods and essentials such as paper, textiles, meet all the world’s energy needs and clean the atmosphere – all at the same time – our old stand-by that did it before: Cannabis hemp… marijuana!” Jack Herer 1990
