As new suburbs of the city expand and develop, developers take initial responsibility for the planting of trees on grass berms adjacent to roads and streets.
Developers also require approval from Hamilton City Council's Parks and Open Spaces Unit before they undertake any planting.
To find a balance between achieving a quality streetscape and ensuring essential infrastructure and utility services are protected, we need to make sure the right species are planted in the right locations.
We've compiled a list of Council-approved tree species approved for tree planting in Hamilton streets. This list has been developed to guide staff and developers in tree species selection. Species may be substituted at the discretion of our Parks and Open Spaces Unit.

The list details each species' characteristics, such as colour and size at maturity, helping you plant the right tree in the right place.
Some factors to guide species selection are:
Road type and neighbourhood character
When selecting a species of tree, consider the roading hierarchy: arterial roads able to accommodate larger species, and smaller species being more appropriate for local roads. Existing or intended neighbourhood character should also be considered.
Berms 1m-1.5m wide are considered narrow berms and suit a smaller tree species, while wide berms of 2m wide or more able to accommodate larger species.
Species selected for planting should be appropriate for specific site conditions. Certain species are more tolerant of dry, well-drained, while others are better planted wet soil or more suitable to windy and exposed sites.
Size at maturity
This is especially important for trees planted below or near power lines and services. Form and structure should be considered, as some vase-shaped trees are appropriate for planting alongside footpaths – but trees with multiple trunks, or which develop a wide spread of branches, are not suitable and can create hazards and risks for Council, other service providers, and of course residents.
Tree species producing fruit or large seeds may not be appropriate due to the increased maintenance and hazard for pedestrians. As a general rule, we ask developers not to plant tree species which drop fruit products, seeds or pods.
Diversity in the urban garden
A variety of species will limit pest and disease potential and enhance the city's resilience to invasive pests and diseases.
Council's Infrastructure Technical Specifications provide guidance on specific planting methods and maintenance standards for street trees and are available here.
