What specific data quality issues (that mean Housing First figures are "subject to revision due to data quality issues") have been identified, and by what date does the Ministry expect rough-sleeping reporting to be reliable?

Answer

The cohort in Housing First have complex and non linear pathways through the service, with households frequently moving between different states of engagement, housing status, and support needs. As a result, the data represents a dynamic system where flows can change significantly over time, and these changes are unable to be fully captured within single point-in-time reports. Each month the latest three months of Housing First data will be revised to capture any data that may be updated after the reporting period, including any changes in housing status. There is no confirmed work to change Housing First reporting at this stage.
