There are two primary breed registries that are member driven,
non-profit associations and serve breeders in North America: the   
American Kiko Goat Association and the International Kiko Goat
Association.  The National Kiko Registry was created in 2011 to give Kiko
breeders of every size and management style the opportunity to register
and track their genetics through an independent, professionally run, for
profit, livestock registry.

History The Kiko goat was developed exclusively by Goatex Group
Limited, a New Zealand company which has been solely responsible for
the breeding of Kiko goats in New Zealand. The company of large farmers
were actively involved in the capture and farming of New Zealand's
extensive native goat population. All members of the company had a
vigorous and ongoing interest in meat production as a consequence of
which several thousand of the most substantial and fertile native goats
were allocated to a breeding program in which population dynamics
would be rigorously applied to produce a goat with enhanced meat
production ability under browse conditions.

New Zealand native goats New Zealand has a large population of feral
goats which roam unrestrained through the wooded hill country and
mountain scrubland of both islands. These goats derive from the original
imports of British milk goats introduced in the late eighteenth century to
provide sustenance for whalers and sealers prior to New Zealand's
colonization. Over time they have been supplemented by escaped and
released domestic goats turned loose into unproductive scrubland during
times of agricultural adversity, particularly the depressions of the 1890's
and 1930's.

Small colonies of hair producing goats were found in a remote part of the
North Island's Waipu Forest in the 1970's, the legacy of a failed attempt
to establish a mohair industry during the First World War. New Zealand's
total lack of predators and temperate climate meant that native goats
have been able to breed without the strictures of mortality that are found
elsewhere in the world. In addition, they rapidly adapted to the
environment into which they had been released and established
themselves throughout the country. As a consequence, comparatively
small numbers of goats released into the wild had burgeoned to hundreds
of thousands of goats by the mid 1970's. Goats (along with deer) were
ravaging New Zealand's native flora to the extent that the government
permanently employed substantial numbers of professional hunters in an
effort at control.
100% New Zealand — All animals designated as 100% New Zealand must
be the offspring of 100% New Zealand goats that can trace their pedigrees
to the original New Zealand imports and have no other animals in their
pedigrees.

Purebred — All Kikos designated as Purebred must be at least 15/16 or
93.75% Kiko blood. No progeny of Purebred animals shall be registrable as
100% New Zealand. 100% will be used when calculating the breed purity of
a Purebred buck’s or doe’s percentage Kiko offspring.

Percentage — All animals designated as Percentage animals must be at
least 1/2 (50%) Kiko and must be the offspring of a registered 100% New
Zealand or Purebred Kiko buck or doe. Only does may be registered in the
Percentage Herd Book.  The percentage classifications are 50%, 3/4, 7/8,
15/16 which is considered purebred.  All offspring of 7/8 percentage does
are considered and registrable as purebred Kikos.
