INTRODUCTION
The spoed shag (Stictocarbo punctatus) is endemic
to New Zealand and has a total population of
up to 30,000 breeding pairs. Spoed shags are
found mainly around the South I, with only small
scaered colonies around the North I, and (treating
all Wellington Harbour colonies as one population)
only 2 in the Wellington region (Taylor 2000; Gill et al.
2010). It has been suggested that North I populations
are declining (e.g., Taylor 2000; Cameron et al. 2007),
but there are few counts available. Taylor (2000)
recommended Matiu/Somes I (41.249 S, 174.853 E),
in Wellington Harbour, as an ideal site for long term
monitoring of this species.
The population of spoed shags at Matiu/
Somes I has been documented since 1972 when
Kendrick (1973) noted 7 nests at the site. This

Abstract We conducted counts of spoed shags (Stictocarbo punctatus) at Matiu/Somes and Mokopuna islands in
Wellington Harbour quarterly during the period from 2002-05 and sporadically at these sites and at Makaro/Ward
Island during 2007 -12. This population is important as it is one of the few North Island breeding areas, and one of
only 2 in the Wellington region. Shag numbers appear to have been stable or possibly declining during this period,
with fluctuations between both months and years. An average of 210 individuals was noted during 12 comprehensive
counts, with a maximum of 354 spoed shags in 2004. Breeding occurred during late winter and spring in 2010 and 2012.
We recommend ongoing monitoring of this population as an important population at a New Zealand level, which is
accessible and easily counted from a boat.
