Have your say
From 30 November 2023 to 25 January 2024, the Ministry for Primary Industries (MPI) wants your feedback on proposed changes to the import requirements for mangosteen and rambutan plants for planting.
On this page we explain how we plan to prevent harmful pests being introduced to New Zealand when these plants are imported. Our previous import requirements did not manage biosecurity risks appropriately. We suspended all imports of these plants so we could re-evaluate the risks and how to manage them. We have now done that evaluation and want to update our requirements so that people can start importing these plants again. We'd like to hear your thoughts.
We base our requirements on the best scientific evidence available to us at the time. If you know of anything that could change our conclusions, whether scientific evidence or your own industry experience, include this in your feedback.
Why we are doing this
In recent years, tropical plants have emerged as an interest area for many people. More and more New Zealanders have been asking us about importing tropical plants. We are unable to assess the risks of all the tropical plants people want to import because risk assessment takes a long time. However, we have reviewed 2 plants in this interest area: mangosteen and rambutan.

Currently, no one can import mangosteen or rambutan plants. In the past, we required mangosteen plants to comply with the general requirements that apply to all plants for planting. We also had some special requirements for rambutan plants. However, no one imported these as plants for planting, and so we did not review our requirements for many years. Now people want to import them, and we are updating our requirements so people can import them safely.
- You will be able to import 2 mangosteen species (Garcinia mangostana and Garcinia xanthochymus) from Malaysia and one rambutan species (Nephelium lappaceum) from Malaysia and Thailand.
- You will be able to import bare-rooted whole plants, leafless semi-hardwood cuttings, and tissue cultures.
- To manage the risks of pests, we propose having plants inspected when they arrive in New Zealand and as they are growing in post-entry quarantine. We will also need to test for some pests.
We have identified 16 key pests that could be associated with imported mangosteen and rambutan plants and pose a risk to New Zealand if nothing is done to prevent the pests entering. Four of these pests are associated with mangosteen and 12 with rambutan.
The new import requirements we're proposing will reduce the biosecurity risk to a negligible level. The new requirements are outlined in this consultation.
Based on our assessments, we came to the following conclusions:
- The biosecurity risks of bare-rooted whole plants and leafless semi-hardwood cuttings of mangosteen and rambutan need to be managed by Level 2 post-entry quarantine with controls on irrigation. Testing will also be required for some pests in post-entry quarantine.
- The biosecurity risks of mangosteen and rambutan tissue cultures (plants in vitro) derived from new aerial parts of the plants can be managed by Level 2 post-entry quarantine.
- We should require at least 3 shoot flushes in post-entry quarantine. Three shoot flushes indicate that the plants have been in continuous active growth. The flushes also indicate that suitable environmental conditions are being met in post-entry quarantine for the plants to grow and for pests to express symptoms if present.
We're happy to discuss the changes we're proposing at any time during the consultation period. To arrange a phone or video call, email firstname.lastname@example.org
You can give us feedback by completing our online survey or by emailing us.
If you are making a submission by email, send it to email@example.com
We must get your feedback by 5pm on 25 January 2024.
What we want to know
We want to hear your feedback, technical information, industry knowledge and suggestions on:
- the measures we're proposing
- the feasibility of importing under the proposed requirements
- this approach to consulting you.
30 November 2023 to 25 January 2024: First consultation on proposed changes.
20 February to 12 March 2024: Second consultation on a draft import health standard.
Late March 2024: Final import health standard issued.
We will consider your feedback on our proposed changes and then draft an import health standard.
We intend to provide a second chance for you to have your say when we send the draft standard to you in February 2024. We will value your feedback on that draft.
We will read and consider all feedback on the draft standard and make any changes we need to before we publish it in late March 2024.
