           Kapiti                   Kapiti Island is a dramatic icon along our Kapiti Coast. It stands sentinel at the
                                    northern entrance to Cook Strait and is a sanctuary for native animals and the human
         Island—                    spirit.
        offshore                    Kapiti Island has an area of 1965 hectares and is 521m at its highest point. The island
                                    was largely cleared for farming in the 1800s but has been regenerating into native
        paradise                    bush since 1887 when most of the island was declared a nature reserve. Possums
                                                                                 were eradicated by 1986 and rats in

         Hihi/                      Hihi or stitchbirds have quite the sweet tooth!

   sweet tooth                      kaka. Feeders are filled every three to four days to ensure a constant supply.
                                    Numbers of hihi have increased for the third consecutive season. The 2003/04
                                    breeding season was very busy indeed with all known adult females attempting to
                                    breed. At least 46 youngsters left the
                                    nest and it is hoped that they will have
                                    young of their own in upcoming years.

                             Dave Wrightson, DOC Kapiti Island Field Centre Supervisor, promoted safety and
                             helpful hints about the marine reserve during radio broadcasts. Starting in December
                             and running through March, educational broadcasts covered safety tips, use of correct
                             nautical charts, tide statistics, proper use of anchors in the area, weather information,
                             guidelines about marine markers, and advice on trolling.

                                      a special guided excursion. Once on Kapiti Island, students joined Dave Wrightson
                                      on the DOC boat for a guided tour of the marine reserve. They experienced sea life
                                      along the western side of the reserve by viewing fish and seaweed through the
                                      portable underwater camera. A highlight of the boat ride was observing New Zealand

                                      Fiordland in 1948. With fewer than 200 birds in the wild, island introductions are

                                      On Kapiti some takahe like to take a winter holiday. One pair breeds at their grassland
                                      home at Rangatira (near the interpretive centre). At the end of the breeding season
                                      they take their family to Taepiro (middle of the island, 350 m altitude). This year
                                      they reared one chick and in February trekked again to the slopes of their Taepiro

                                      Greg Moorcroft, DOC ranger, monitored another pair of takahe which raised twins
                                      at the north end of the island.

                                 • Education about the issue
                                 • Permanent bait stations on the islands
                                 • Annual rodent audits
                                 • Control of weeds when necessary
                                 • All visitors check packs and
                                      equipments for pest weeds or
                                      animals before arriving to the island
                                 • Ensure all fruit pips and vegetable

                                 developed. One garden required the relocation of approximately 4 tonnes of beach
                                 shingle. These gardens include threatened plants and also examples of island flora
                                 that may not be seen on the public tracks.

           Mana                  Mana Island is a 217 ha scientific reserve which has seen many changes in its colourful
                                 history. An early Sydney merchant, John Bell, brought sheep and cattle to the island
        Island’s                 in the early 1820s. The cattle were used to supply milk and beef to the whaling trade
       colourful                 which had become a fairly large industry in the area. Later John Bell died suddenly.
                                 No planks could be found for a coffin so friends buried him in a rum barrel on the
         history                 Island.
                                 Disease found in some of the sheep on the island in 1978 was sduspected to be
                                 scrapie, so the island was placed under strict quarantine for the next five years. All
                                 stock were removed from the island in 1986 and a year later Mana was named a
                                 scientific reserve. Mice numbers exploded once stock were removed; estimates
                                 suggest 5 million mice were present before they were eradicated. Today a variety of
                                 native plants and animals can be found and new species are being introduced back
                                 to the island as part of an island restoration plan.


      Sardine                    One hundred fairy prion chicks and fifty speckled skinks arrived on Mana by
                                 helicopter in January. Five week old fairy prion chicks and adult speckled skinks were
    smoothies                    caught on Takapourewa (Stephens Island) where they are found in substantial
       served                    numbers.
                                   Once on Mana a team of hardy
                                 volunteers braved storms and went
                                 without sleep to ensure the five-week
                                 old chicks, in their cliff-top burrows,
                                 were in top condition to leave their
                                 artificial homes. These surrogate parents
                                 spent endless days collecting, feeding
                                 and weighing the birds. Tins of

                                 The fifty speckled skinks may one day use the seabirds’ burrows for shelter and to
                                 find insects. Speckled skinks hunt during the day and should not compete for food
                                 with the already established McGregors skinks which hunt at night.
                                 The project has been made possible by the efforts of the Friends of Mana Island
                                 (FOMI) that have been supportive of many projects on Mana and is also supported
                                 by Ngati Toa, Ngati Koata and DOC.

                                        Twenty-six yellow-crowned parakeets and 80 flax weevils are adjusting to their new
                                        homes after being released on Mana on 12 May. Members of Friends of Mana Island
                                        (FOMI), Ngati Kuia, Ngati Toa and DOC worked stealthily both night and day to
                                        capture their quarry from Chetwodes and Maud Islands.
                                        Nearly invisible mist nets were used to trap both male and female parakeets on the
                                        Chetwodes. Birds were held in a temporary aviary before being placed in wooden
                                        carrying cases for their helicopter flight to Mana.
                                        Ngati Toa representative, Tama Coker, blessed the parakeets as they flew out of their
                                        boxes into the surrounding scrub. The manuka forest soon came alive with the
                                        chirping sounds of the new arrivals.
                                        Humans became nocturnal on Maud as they searched the island for the large flightless
                                        flax weevils. Adult weevils retreat deep into the base of flax bushes during the day
                                        making them nearly impossible to find. When seen at night under torch light, the
                                        weevils become motionless. If the flax leaves are disturbed then the weevils drop to
                                        the ground making them difficult to find.

 Worth their                Southern right whale sightings are worth their weight in gold. This mammoth yet
                            elusive marine mammal is listed as nationally endangered and DOC is asking for the
  weight in                 public’s help in recording sightings of these whales.
       gold!                Southern right whales once kept colonists awake at night with their noisy mating
                            antics during the 1880s. However their population was decimated by whalers.
                            DOC is seeking sightings so it can confirm historic data against its record of known
                            individuals. Anyone who sees a southern right whale is asked to immediately phone
                            0800 DOCHOTline (0800 362 468), available 24 hours. DOC would like to know the
                            date, time and location of the sighting; the number of whales and whether there are
                            any calves; and the direction they were travelling.
                            Adult whales are 14–15m long on average and calves between 4.5 and 6m. They are
                            mostly black in colour and can be identified by their V-shaped blowhole spray, white
                            growths on their heads called callosities, and their lack of a dorsal fin.

       Mana’s               There are currently 31 takahe on Mana Island consisting of six breeding pairs plus
       takahe               one family group of five adults. There are four chicks which are now over six months
                            old. Takahe were fed supplementary food pellets at the start of the summer to assist
                            them with their breeding success.


Staff profiles              Dave Wrightson lives on Kapiti Island with his partner Jackie McIntosh and their son,
                            Yuri. Dave and Jackie were previously fisheries observers before coming to Kapiti
                            Island in 2001. Dave is the field centre supervisor for the island and conducts marine
                            reserve patrols and day to day activities. Jackie is building and maintaining the

                                  The idea of island reserves to protect rare birds was first suggested in the 1870s,
                                  but by the time the first were established, 20 years later, many birds had already
                                  become extinct. DOC aims to restore species within their ecosystems as part of
      For more information        its biodiversity strategy. One way to achieve this is through island restoration.
