Im assuming you got 45Deg roof pitch being where you are ? . Without seeing your chimney and your heating appliance , my advice is to make a roof crawler and clean from above . Remove baffles (the bit on the roof of the inside of the fire box) .Then remove the cowl . I got a commercial brush and rods you can borrow from ChCh if you want (runs on 6 heineken per week negotiable). Easy as gently push brush down the flue adding extensions as you go . As said above most soot is at top of the flue . You can use a chain ( ball it up aprox size of the flue 150mm . use wire to hold its rough shape . Attach balled chain to a rope and drop and raise , works well enough . Be careful if there are offsets (bends) as brush or chain can get stuck and damage flue or seperate it . Take some photos if you want it may help with advice given .
