In many cases in which specimens are not available to confirm species identification, the name pacificus may refer to maculatus. When only the latter occurs the interpretation is obvious, but in areas of sympatry (most of the North Island) this determination cannot be made.

In many cases in which specimens are not available to confirm species identification, the name pacificus may refer to maculatus. When only the latter occurs the interpretation is obvious, but in areas of sympatry (most of the North Island) this determination cannot be made. Such references are discussed in the comments for H. pacificus. In most cases statements apply to both species. H. maculatus is distributed throughout New Zealand with the possible exception of the North Cape region (McCallum 1981, but see Pickard & Towns 1988) and a number of offshore islands (Fig. 42). Known island localities include D'Urville Island (Buck- ingham & Elliott 1979), Stephens Island (Werner 1901; Walls 1983), Trios Island (Werner 1901) and the Stephenson Island group (McCallum 1982b) in Cook Strait, Bird Island and Green Island (Foveaux Strait) (Thomas 1982a) and many northern islands (McCallum 1982a; Bauer 1986; Towns & Robb 1986). Notable island groups lacking this species are the Poor Knights, Three Kings, Mokohinaus and Stewart Island proper (there is a single, doubtful record from Stewart Island — SMI —3). On all nor- thern island groups except Whale Island, H. maculatus is sympatric with H.
