Officials say there is no cause for alarm over a staff meeting called at Buckingham Palace.
The Daily Mail reported it was an emergency meeting, and said all staff from all the royal residences would be addressed by the Lord Chamberlain and the Queen's private secretary, Sir Christopher Geidt.
A member of the Queen's press office told RNZ it was "rare but not unprecedented" for such a meeting to be called, and ruled out a royal death.
They confirmed a meeting was taking place at the palace.
A source told Reuters there was "no cause for alarm" and said details would be released when the meeting ended.
Prime Minister Bill English said he had not been briefed on anything regarding Buckingham Palace.
Both the Queen and her husband, Prince Philip, attended public engagements yesterday.
