The New Zealand flag flies from on top the beehive – the building which houses the New Zealand Cabinet (the Prime Minister’s office is on the top floor).
While politicians can spend a career working to reach a position where they get an office there – it is as a building reportedly not the greatest place to work. The circular interior is an inconvenient shape, it is very disorientating trying to find an exit when leaving one of the (very small elevators). Despite a refurbishment, some Cabinet Ministers still prefer offices in the more modern adjacent Bowen House.
Nonetheless the ninth floor office is a symbol that you are indeed “on top”
