Suspicious packages have sparked a major emergency response and evacuation of some foreign consulates across Melbourne, including New Zealand, with embassies in Canberra also hit.

Diplomatic offices in Melbourne for countries including Germany, Italy, India, Spain and Korea were among those attended by police, fire crews and ambulance officers on Wednesday afternoon.

MFAT confirmed NZ was caught up in the emergency.

"The New Zealand Consulate General in Melbourne received a suspicious parcel this afternoon. Staff were evacuated from the Consulate as a precautionary measure.

The Australian Federal Police and Melbourne Fire Department are investigating."

An Australian Federal Police statement said police and emergency services have responded to suspicious packages delivered to embassies in Melbourne.

"The packages are being examined by attending emergency services.

"The circumstances surrounding these incidents are being investigated."

It is not yet known which embassies in Canberra have been affected.

Two fire trucks, a hazardous materials vehicle and police cars attended the Consulate-General of India on St Kilda Road where staff were evacuated, telling reporters they had been told not to comment to reporters.

They were allowed to re-enter the building, which was deemed "safe" by Vic Emergency by 3pm.

The Vic Emergency website lists more than 10 "hazardous material" events occurring across Melbourne, which began unfolding from about 1pm.

Addresses for the events included Market Street, Bourke Street, Middleton Lane, William Street, and St Kilda Road in Melbourne, Elgin Street at Carlton, and Yertchuk Avenue at Ashwood. Each location matches the address of a consulate.

Emergency workers wearing chemical suits were seen entering some of the buildings.

Some of the events have subsequently been listed as "safe" and "under control".
