Tracking progress of the One Billion Trees programme

Find out about the Government's One Billion Trees programme and how many trees have been planted so far.

A billion trees by 2027

The Government has set a goal to plant a billion trees in the next 10 years – between 2018 and 2027.

Initial estimates suggest about half that number will be achieved through existing planting programmes. The Ministry for Primary Industries (MPI) will be helping boost planting rates to achieve the goal.

It will take a combined effort by government, landowners, commercial foresters, conservation groups, regional councils, iwi, communities, and others.

Keeping track of progress

We'll be keeping track of the progress towards the billion trees goal. Te Uru Rākau collects data throughout the year on the sale and distribution of exotic and native tree seedlings. We'll use this data to estimate the number of trees being planted and update this web page regularly.

What trees are counted?

There's no universally recognised definition of what a tree is, either botanically or in common language.

For the purpose of our tree count, we’re defining a tree as a woody perennial plant species that can grow to a height of at least 5 metres.

Do you think we've missed a species?

We've tried to compile an exhaustive list but we may have missed a species or included a species in error. If you think we have made an error in our species list or if you would like more information on our tree count method, email
