Trees and power lines in Christchurch
Don't trim it yourself, and keep ladders and poles well away. Treat the line as live. Ring Orion, because nobody may work within 4 metres of its lines without a close approach consent. If a line is down or sparking, call 111.
Hedge trimming in Christchurch: what's local
Your side of the boundary
Council says growth poking through fences or hedges should be cut back to the property boundary line. Who looks after a hedge depends on where its base sits.
Footpaths and roads
Overhang must clear 2.5 metres above footpaths and berms, and 5 metres above the road. If a hedge blocks a footpath, road, sign or waterway, council gives a limited time to fix it, then can arrange the work and charge you.
Shelter belts on lifestyle blocks
Out toward the plains, the hedge is often a macrocarpa shelter belt. Macrocarpa tolerates drought, frost and salty wind, but some strains get canker (a fungal disease that kills branches and leaders). Cypresses can also cause abortion in pregnant cattle, so think about where clippings land if stock graze next door.
Under rural lines
Orion lists shelter belts among the exceptions to the low height planting rules that start on 23 July 2027. Separately, from 17 October 2026 nothing may overhang any line outside urban areas, so a tall belt under rural lines needs Orion's attention.
How hedge trimming works in Christchurch
Most hedges cope better with a light trim through the growing season than one hard cut a year. Privet and box are forgiving. Conifers such as macrocarpa are not: cut back into old, bare wood and they often stay brown.
Shape matters in a windy city. A hedge cut slightly narrower at the top than the bottom lets light reach the lower branches, so it stays thick at the base instead of going bare and leggy.
For a hedge that's got away from you, a staged reduction over two or three seasons usually beats one drastic cut. The hedge trimming page covers removal and replanting.
Neighbours' trees in Christchurch
Council won't mediate between neighbours, so a shared hedge comes down to a conversation. You can cut back a neighbour's growth that crosses onto your side, as far as the boundary. If talking fails, the neighbours' trees guide explains the District Court route under the Property Law Act 2007.

Hiring an arborist for hedge trimming in Christchurch
Trim the street side first, to the 2.5 metre footpath clearance, because that's the part council can act on. Agree a height with the neighbour before anyone books a big reduction. And for a shelter belt anywhere near lines, call Orion before you call anyone else.
