Tēnā koe John
Response to your request for official information Thank you for your request under the Official Information Act 1982 (the Act) to the Ministry of
Health – Manatū Hauora (the Ministry) on 5 November 2025 for information regarding the
Kostaive COVID-19 vaccine.
The Ministry notes that on 11 October 2025, Pharmac – Te Pātaka Whaioranga also partially
transferred questions 3 and 4 of your request to the Ministry (H2025075357 refers). For ease of
reference, we have merged your requests and have addressed both in this letter. You requested:
1. Regulatory status
Has Medsafe received any application for approval, provisional consent, or
importation of the product known as Kostaive or zapomeran for distribution or
administration within New Zealand?
•
If so, please provide the date the application was received, its current status,
and the sponsor name(s).
•
If no application has been received, please confirm that fact.
2. Administration and distribution
Has Kostaive (or any formulation containing zapomeran) been imported into,
distributed, or administered within New Zealand under any authorisation, including
provisional consent, clinical trial, compassionate access, or emergency use
provisions?
If yes, please provide:
•
the date(s) and authorisation type(s);
•
the quantity imported or distributed; and
•
any associated adverse event reports (in anonymised or aggregate form if
appropriate).
3. Clinical trials
Are there any registered or approved clinical trials involving Kostaive or zapomeran
currently active or completed in New Zealand?

•
If so, please provide the trial reference numbers, sponsor names, and trial
status, and any associated documentation.
4. Communication and assessment
Please provide any internal Medsafe or Ministry of Health communications, briefing
notes, or assessment summaries referencing “Kostaive,” “zapomeran,” or “CSL
Seqirus / Arcturus Therapeutics” since 1 January 2023.
Medsafe can confirm that no clinical trials for Kostaive have been conducted as the medicine is
not approved in New Zealand. As such, your request is refused under section 18(g)(i) of the Act,
as the information requested is not held by the Ministry and there are no grounds for believing
that the information is held by another agency subject to the Act.
If you wish to discuss any aspect of your request with us, including this decision, please feel free
to contact the OIA Services Team on:
[email address]. Under section 28(3) of the Act, you have the right to ask the Ombudsman to review any decisions
made under this request. The Ombudsman may be contacted by email at:
[email address] or by calling 0800 802 602.
Please note that this response, with your personal details removed, may be published on the
Ministry website at:

information-act-requests. Nāku noa, nā
