Our understanding of the diversity of gastrointestinal endoparasites affecting tuatara is inadequate as many of the parasite ova seen could not be identified. This is the first record of tuatara as a host for Trichomonas spp of protozoa in the gastrointestinal tract.

Faecal egg count reduction tests were used to identify a strain of Ostertagia circumcincta/trifurcata complex in goats which was resistant to: ivermectin (at 0.2 mg/kg and 0.4 mg/kg orally), oxfendazole (at 5 mg/kg orally), levamisole (at 12 mg/kg orally) and fenbendazole (at 5 mg/kg orally) combined with levamisole (at 9.4 mg/kg orally). The percentage reductions achieved in these faecal egg count reduction tests were respectively 27%, 83%, 82%, 79% and 82%. Moxidectin (at 0.2 mg/kg by subcutaneous injection), fenbendazole (at 10 mg/kg orally) combined with levamisole (at 18.8 mg/kg orally), ivermectin (at 0.4 mg/kg orally) combined with oxfendazole (at 10 mg/kg orally) and ivermectin (at 0.4 mg/kg orally) combined with levamisole (at 12 mg/kg orally) were effective in removing these nematodes in goats as determined by faecal egg count reduction tests. These drenches achieved reductions of 100%, 100%, 98% and 100% respectively.

The number of alpaca infected with Mhl was low, as was the seroprevalence of BVDV. Gastrointestinal parasitism was, however, a common finding in this sample of New Zealand alpaca.
