An extremely simple map, with no name labels at all.
It is slightly later than the 1988 map (Wellington Zoo map 1988 | ZooChat) - the otters have moved from by the Aquarium down to the entrance (where they are still exhibited today). It is likely to be 1989 or 1990. There is still a bear depicted - the last Asiatic Black Bear died in 1987 or 1988, and the last American Black Bear was taken off-display in 1991 (so that the bear terraces could be renovated for Sun Bears). Otherwise the two maps appear extremely similar in terms of species.
