Police are today (3 Dec) responding to another spate of emails of 'a concerning nature' sent to organisations throughout New Zealand, including hospitals and places of worship.

While any threat received will be treated with the appropriate caution, Police said they have not yet established any actual threat at this time.

Police said staff were working with those impacted and each organisation may respond differently according to their individual circumstances and the information available to them.

The emails were similar to those received by a number of organisations on 23 and 24 November, they said.

Police are still working to establish the origin of the emails.

Any organisations who receives the emails should report them to Police.
