Aotearoa New Zealand is not well represented by native terrestrial (land) mammals with neither of the two species of bat being recorded in the area. Introduced exotic species however, are an ever present problem with Brown and Black Rats, House Mice, Weasel, Stoat, Ferret and Hedgehog being the main culprits, all capable of impacting on local wildlife. Some control of the species takes place around areas of the Ramsar site'such as Fernbird Flats but little is done elsewhere.

Marine mammals are more numerous around the coasts and several species can be seen at certain times of the year. Sightings can be useful to record so if you are fortunate enough witness these enigmatic creatures please report using this form.
