Fall Distance Trees in a possible future; a question of tree regulations


‘Out of Zone Trees’ are the biggest threat utility arboriculture has faced in the last 145 years. Or are they? In this talk Mark Roberts will look at the key  points of MBIE’s review of the Tree Regs. We’ll consider the problems, the players and the solutions. It is a complex problem and our problems are not  ours alone.

In this presentation we shall look at the Tree Regs twenty years on - the Electricity (Hazards from Trees) Regulations 2003. We shall look at what Ministry of Business, Innovation, and Employment (MBIE) proposed in the latest of many reviews. We shall consider what the Electricity Engineers' Association (EEA) and the Electricity Networks Association (ENA) wish for, what NZ Arb suggested and then just because we can, I shall propose something completely different.
