In reality, the Queen’s Chain is a term describing what is now generally accepted as the marginal strips of land or esplanade strips, which are normally 20 metres wide and adjoin many lakes, rivers and the foreshore. It can also include land which has been retained by the Crown for conservation purposes. These lands are usually controlled by the Department of Conservation. In some instances, this means there are restrictions on public access. These restrictions are most commonly imposed to protect sensitive areas or endangered animals.
However, there is still a large amount of privately owned land around New Zealand which has no Queen's chain or esplanade strip. The private rights attached to such land are referred to as “riparian rights” and usually extend well into the water, granting unrestricted private access to the owner. In any event, whether the land is considered to be part of the “Queen’s Chain” or privately owned, government imposed legislation still applies.
The Queen’s Chain becomes a topic of contention when it comes to public access to waterways and bush and there is often an assumption that the Queen’s Chain applies; when in many cases it does not. Archives New Zealand holds records for all Crown land (including land subject to the Queen’s Chain) which can be ordered and/or viewed in person.
