Fencing

Sheep netting
Sheep netting is the quickest and easiest to put up. If you live near numerous lifestyle blocks, you may want to create a degree of dog resistance (and lamb retention) by adding chicken wire to the netting.

Lighter guages of sheep netting can also be split down the middle to create 450 mm wide lengths to add to the top of the standard 900mm high fence. This additional height adds to dog resistance without the cost of using full height deer netting. It also thwarts 'jumpers', especially nervous 'arapawa' sheep. 

Heavier guage sheep netting might be prudent for perimeter fences if you have reason to keep a 'flighty' individual. A sheep running at full tilt with neck outstretched can burst through some lighter gauge nettings.

Straining sheep netting is a bit of a mystery, and while it is possible to get  some wires tight, unless you have the special tool for straining netting, there are inevitably some wires that are loose. Learn to live with it, or pay a contractor.

Sheep will put their heads through the netting and lean against it hard to get at that last little mouthful of grass just out of reach on the other side of the fence (no matter how fresh the pasture is on their own side). This tends to slacken the netting a bit. Either live with it, or herbicide spray the outside perimeter of the fence so there is nothing for the sheep to be attracted to.

Temporary fencing
It would be very useful to be able to allow sheep into a fairly narrow orchard row of more shrubby fruit trees such as citrus - without having to worry about them stripping the foliage. Using temporary electric fencing  consisting of multiple tapes would not be worth the hassle.

Recently, a lightweight electric net ('Hot Net', phone 07 867-3091) has come on the market. It has 9 electrified horizontals, and non-electrified verticals. It comes with lightweight push-in posts, and a 50 metre roll, posts included, is light enough to carry in one hand. This might turn out to be the answer to the bushy fruit row grazing problem.

Another product, the 'electranet' is similar, and also portable. Electranet earths well, even in dry conditions. It is similar to sheep netting, except made of a polythene fibre with stainless steel intertwined. The verticals are semi-rigid. It is supplied with 15 insulated push-in posts. The makers claim the standard 50 metre length can be erected in 10 minutes and taken down in 5 minutes.
