Agencies can be found in the Schedule to an Appropriation Bill (budget), Schedule to FMA Regulations and/or Public Service Act.

When defining the hierachy, this system is designed towards monitoring accountablity. Thus large agencies that have registered their own ABN 
and have their own accountablity mechanisms/website recieve a seperate record as a child of their department.
Some small agencies will choose to simply rely on their parent department's accountablity measures.
 
This flows through to organisation name and other/past names. A department that accounts for an agency will list that agency as an other child name.
As agencies themselves shift between departments, there may be scope for providing time ranges but typically the newest hierarchy will be the one recorded.
A department/agency name will be the newest active name assigned to that ABN.
