What does it look like?
Banana passionfruit is a vigorous, evergreen, and high-climbing vine. It grows up to 10 metres high with long, hairy stems which have many spiralling tendrils. Leaves have three lobes (each lobe 5-14 cm long) with the middle lobe being the longest. Leaves have a furry underside and serrated edges.
They have pink, hanging flowers (7 cm diameter) with a central tube (6-9.5 cm long) appear, followed by hanging, thin-skinned fruit (up to 12 x 4 cm in size). Fruit ripens from green to yellow or orange, with sweet edible orange pulp and dark red seeds (4-6 mm long).
Most commonly found in disturbed/high light areas of forest and forest margins, however it can also invade the coastal environment.
Why is it a problem?
It grows rapidly in most soil types and produces highly viable seed within two years. It’s relatively tolerant to shade, damage and drought, and they take root touching the ground.
It generally reaches climax growth in the medium-high canopy section of the forest, where it forms large masses which weigh down on canopy species and block out light, preventing establishment of native plants and causing canopy collapse. After this, other weeds can easily invade due to the high light levels and disturbance.
Control methods
Physical control
Hand pull whenever possible or dig plant out at the roots. Cut off above ground or tie stems in air to prevent layering.
Herbicide control
Cut and stump treat larger stems with metsulfuron-methyl (600g/kg e.g. Escort®) at 1g/L water. Or, glyphosate (360g/L e.g. Roundup ®) at 200ml/L water. Or,
Spray masses on the ground where roots can’t be pulled with triclopyr (e.g. Grazon®) at 6ml/L water + penetrant, or glyphosate at 10ml/L water + penetrant.
CAUTION: When using any herbicide or pesticide, PLEASE READ THE LABEL THOROUGHLY to ensure that all instructions and safety requirements are followed.

Management Programme
National Pest Plant Accord (NPPA)
The NPPA is designed to prevent the sale, distribution and propagation of a set list of pest plants (the Accord list) within New Zealand. If allowed to spread further, these pest plants could seriously damage the New Zealand economy and environment.
More informationUnwanted Organism
An unwanted organism is any organism that's capable of causing harm to natural or physical resources (like forests and waterways) or human health. A number of introduced pests in New Zealand are classed as unwanted.
Organism of Interest (OOI)
Organisms of Interest are those specified as pests under our Regional Pest Management Plan that are capable of causing significant adverse effects on one or several of our Regional values. These species warrant being watch-listed for ongoing surveillance or future control opportunities.
