Fencing your site
Part of your land preparation activity for planting trees is getting fences set up. The type of fencing you need depends on your terrain, what you’re planting and what you want to keep away from your trees.

Before you fence your site
There are things to you need to think about before you put in a fence:
- Do you have a natural boundary?
- Do you have waterways or wetlands?
- Will your new fence allow access to maintain your plantings?
- Are you planting near an existing fence line or modifying your borders to where you want to plant?
- Are you upgrading an existing fence to make it stock proof?
- What are the costs and benefits of different fences?
- How long do you need to protect your trees? You may only need temporary fencing.
- What access do you or contractors need to your site?
- If you’re planning on harvesting, consider how you’re going to harvest your site.
Is fencing the best option?
When you should fence your site
Fencing is important to keep animals you are grazing yourself, such as sheep and cattle, away from browsing (eating) your seedlings. It can also stop other animals, such as deer and goats, from damaging your trees if you can install a suitable fence.
You should fence before you begin planting. This will give your seedlings a better chance of establishment and survival.
Where you should fence
Build your fences:
- straight up hills rather than around them
- up and down ridgelines
- following logical boundaries.
Tips when building fences
- Build fences in favourable weather conditions. If the weather is too wet, the posts might move and it’s harder to use machinery. If the weather is too dry, it’s more difficult to dig.
- Do not fence where your animals have got higher ground on one side so they can jump over it.
- Waterway fences need to be far enough back to allow for flooding.
Tips when building gates
- Build logical size gateways for your needs. Think about what vehicles or farm machinery you need to fit through. For example, do you need to get in and out for maintenance or do gates need to be large enough for harvesting equipment to get through?
- Allow enough space for vehicles to turn into the paddock.
- Place your gates where your stock naturally runs. For example, gateways in paddock corners are normally easier to shift stock through than gates in the middle of a fence line.
Types of fencing
Your fencing type will depend on what animals or pests you need to keep away from your trees. Common fence types include:
- Post and batten – good for sheep and cattle. Also used for boundary fencing. It is strong and secure but expensive and labour intensive to erect.
- Electric – good for dairy cows. Cheaper, easier, and faster to erect but not as secure and does not last as long as a post and batten fence.
- Wire netting (about 1 metre high) – good for sheep or young stock.
- Post and rail – good for horses.
- Deer netting – good for deer and goats.
Predator fencing can keep everything out by using 5 millimetre mesh and curved guards but is extremely expensive to erect.
Boundary fences
Boundary fences signify the legal boundary of your property and minimum requirements are defined under the Fencing Act 1978.
Reach an agreement with your neighbour as to the type of fence and how you'll share costs. If you want a better quality fence than the minimum specified under law, then you may have to meet the additional costs yourself.
The Ministry for Primary Industries commissioned a report in 2016 which has the regional costs of the different types of fencing.
Not sure on the best type of fence?
Getting the right fence may cost more upfront, but it can work out more cost efficient in the long run. Get good advice before you start. It can be costly and you want to get it right the first time.
Farm supply stores and fencing contractors can offer you advice. Other places you can go to for information include Lifestyle Block and DairyNZ.
Fencing maintenance
Regular maintenance will extend the life of a fence. Fences are cheaper to repair than replace. Regularly check your fence lines for:
- broken or loose wires and battens
- any solid posts that have moved, lifted or broken
- any rusting on post staples (you may need to pull some staples out to check this)
- holes in netting
- shorting out of electric fences
- broken electric insulators.
