The removal of rats has commenced. Two aerial bait drops using
brodifacoum pellets (known as Pestoff 20R) were undertaken during
periods of calm, fine weather in August and September. A number of
people attended the drops as observers and included Maurice Ngatai,
Richard Somerville-Ryan and D.o.C staff from Northland.
I would like to acknowledge Ngati Rehua’s support of the extension of
the aerial baiting programme onto Opakau, Moturako, Sugar Loaf and the
Grey Islands; and to the King family for allowing the same to occur on
Nelson and Motuhaku Islands. I would also like to thank the Port FitzRoy
mussel farmers for their support and a number of landowners on Great
Barrier on whose lands the Motu Kaikoura Trust has installed bait
stations, traps and tracking tunnels to prevent rats from reinvading
Will Scarlett is now completing the installation of a detection and
response system using bait stations, traps and tracking tunnels on
Kaikoura so we have a reliable method of detecting any reinvaders and
catching them quickly. Will’s knowledge of the local area is an
The Motu Kaikoura Trust is in the process of installing signs at key
locations on Kaikoura to let people know the island is soon to be pest
free and how they can help keep it that way.
Motu Kaikoura and its surrounding islands are wonderful scenic spots as
well as homes for many native species, the range and numbers of which
will only increase in the absence of pests. Please help these places
• Checking your boat (including your dinghy) prior to departure—look for
signs of rodents: small black droppings, eaten food, dead bodies(!).
We’d appreciate if you could install a trap and maintain it.
• Not tying up or mooring at the Kaikoura wharf. By all means drop
people off but then anchor a safe distance away and row ashore.
• Not running shore lines onto Kaikoura or any of the surrounding
islands. One of the main ways rats get ashore is off boats and down
mooring or shore lines.
• Leaving your pets at home or on the boat. Species such as sea and
shore birds, brown teal and banded rail are very tempting morsels for
dogs in particular.
• Taking care what you do when you are ashore. Please don’t light fires
or camp on these islands and have a pack it in pack it out rubbish
• Come ashore and enjoy Kaikoura but respect that the smaller islands
that surround it are private property.
