Autumn Baiting Instructions

Hi everyone,

It's time to get ready for our upcoming Autumn baiting round!

The last baiting round was smart baiting (we replaced only the bait which needed to be replaced with a red taped bag and left the good blue taped bait in stations).

This time we will do super smart baiting, with a peripheral buffer zone (two bags in identified stations).

We understand that the peripheral buffer zone involves carrying a heavier load of bait but analysis of uptake shows it was worth it so thank you in advance for your energies!

Below you can see the heatmaps (concentration of bait stations that had more than 1 bag eaten) for the 3 baiting rounds when we did the peripheral buffer zone (click on the picture to see its enlarged version).

You will find all the instructions you need for baiting below.

* baiting programme: when will I need to bait my line?

* does my line (or part of my line) fall within the peripheral buffer zone?

* how do I do super smart baiting?

Also, this baiting round, we will trial another poison at the Ark (Diphacinone). We will test it in the eastern part of the AWN block, so the line owners impacted by this change will be contacted separately. Everybody else will use Brodifacoum - as usual.

A change of bait has been in the pipeline for a while now, in order to follow best practice and be adaptive in our management. We will follow up with more information about Diphacinone, and pending results of the trial in AWN we will use it in other blocks in rotation.

Please don't hesitate to ask Gillian or myself if you have any questions.

Thank you in advance for your help, patience and persistence!

Baiting programme: when will I need to bait my line?

From 5th to 30th of April:

AN block

P block


U block

L block

T block

R lines from R0 to R6 included

F lines from F0 to F6 included

The baiting of the B block is postponed so that the wasps will be gone before people set out to bait their lines.

Please note that the following lines cannot be baited, because they are not accessible due to storm damage:

Auckland City Walk (T15, T16, T17, T18, T19, T20, T21), C lines (C1 and C2), L7, L8, L9 and L10.

The following lines can be baited only if you retrace your steps back, do not cross the stream to reach the southern section of the Auckland City Walk which is fully closed:

AN16S, AN17S, AN18S.

All the other U, L, R and F lines which are usually accessed from the lower section of the Upper Kauri track can be baited only if they are accessed from the upper section of the Upper Kauri track or as a loop with another accessible line.

Please contact us if you would like help planning your route. Alternatively if you feel that the restrictions to access mean that it's not feasible for you to bait your lines please contact us so we can arrange cover.

From 1st to 21st of May:

F lines, from F7 to F17

R lines, from R7 to R20

K block

Gleeson block

D block

W block

B block

AWN lines from AWN0 to AWN6 included - baited with Diphacinone. Please wait for our email.

AWN lines from AWN24 to AWN19&AWS19 - baited with Brodifacoum as usual

From 22nd of May to 18th of June:

AWN7 to AWN18 and 18b - baited with Diphacinone.

AWS block

IW block

KOK block

CGN and CGS blocks

Please let us know as soon as possible if you know that you won't be able to bait your line(s) at the allocated time. We'll try to find other suitable dates with you or we will bait the line(s) for you.

Also please contact us if you have any questions.

Does my line (or part of my line) fall within the peripheral buffer zone?

Some of the Ark bait lines are fully within this peripheral buffer zone. Other lines have only some of their stations within it. There will be a printed list of lines in the store room on the bait container.

Check if your line is on that list and if it is, what type of baiting is required (see description at the top of the list). Take the number of bait bags needed: 2 bags per station which will be double bagged and 1 bag for each of the other stations.

You can also find a copy of the list here.

How do I do super smart baiting

There is currently one bag with either red or blue tape in bait stations.

Therefore, bring back all blue taped bags, even if they are untouched, and replace with one yellow taped bag. Otherwise, blue taped bags will be too old by the time the next baiting round starts in August.

The red bait is fresher, so only change red taped bait if it is more than nibbled or according to the usual smart baiting rules i.e. powdery or mouldy.

The outcome should be one full - or nibbled - bag of good bait in the station. This can be either a red taped bag in good condition, or a new yellow taped bag.

If your line (or station) is in the peripheral buffer zone, in addition to this first step you will add a second bag of fresh bait, so that the outcome is 2 bags in the station.

Take at least two plastic bags to carry the bait: one for blue and rubbish, including red taped bait in bad condition, and another one for more than nibbled red taped bait, so that the latter can be recycled when you bring it back.

Kind regards
