The 1964 health stamps feature the Red-billed Gull (Tarapunga or Akiaki) on
the 2½d stamp - a native of New Zealand, being found throughout the
country and also on outlying islands including the Chatham Islands. The 3d
stamp features the Little Penguin (Korora) - the smallest species of
penguin measuring around 43 cm tall. In New Zealand they are also known as
Little Blue or just Blue Penguins due to their slate-blue
plumage.

Two miniature sheets were issued including eight stamps for
each denomination.

A notable flaw
on the 2½d stamp exists where the registration of the red printing
is offset resulting in a red billed gull with four legs.
