Queen Elizabeth is now the longest reigning British monarch in history, but sometime within the next ten years her reign will end and King Charles will become the UK's head of state. Charles will likely be on the throne for a further 20 years.
Some argue it would be the ideal time to move to a democratic head of state but such an approach is lacks forethought. While it is feasible to wait until events in the UK afford us an opportunity to change, it would be far better to agree on the details in advance and make the improvements at a time of our own choosing.
Queen Elizabeth has let it be known, via former Secretary-General of the Commonwealth Sir Don McKinnon, that she has no problem with New Zealand having its own independent head of state. So it makes sense to make the change why she is still around to enjoy it.
While we don't want to rush the process it is important to be prepared. We need to begin making formal plans sooner rather than later. Change can only happen through binding referenda so it is important everyone has opportunity to discuss and understand what is required.
To work well the planning and public consultation process must be independent of parliament and free from party politics. It is therefore essential to appoint a Head of State Commission akin to the five-member electoral reform commission established in 1985 to examine alternative electoral systems.
