The NZSG Marriages CD was compiled from the original reference numbers that were on the microfiched indexes to the marriage registers held at the RGO office in Lower Hutt, following on from the Matching Brides and Grooms project started by the NZSG. This was done some years ago long before the BMD website came into being, which was set up using a completely different set of references.
Previously when searching through the microfiched indexes the brides and grooms names were separately indexed under their surname. If you knew one but not the other you had to search through until you found the matching number. Very time consuming hence the Matching Brides and Grooms Project.
NZSG did have access to the original registers where required to make sure they had everything covered, so not sure why it would not show up on the BMD website as they supposedly indexed that from the registers.
Although it could be because marriages did not have to be recorded until 1854, and so may have come from a church record held by the NZSG.
