Quick answer
Papa represents P. In harbour, it directs everyone to return aboard because the vessel is preparing to sail. At sea, fishing vessels may use it to report that their nets are caught on an obstruction. These meanings depend on context. See the official New Zealand Nautical Almanac signal chart.

Construction and reproduction
The official identification plate supports the blue field and white centre motif. It does not establish a dimensioned manufacturing specification for this record. Do not derive exact proportions, inset dimensions or colour coordinates by measuring its artwork.
Common manufacture has not been independently documented here. Screen colours would be approximations; a newly drawn illustration would be an editorial reconstruction unless checked against a cited construction standard.
Name and historical context
NOAA identifies Blue Peter as the traditional nickname for the P flag in its educational account.
The preface to Publication 102 dates the first International Code’s publication to 1857 and the effective date of the 1969 edition to 1 April 1969. These are code-history dates, not established adoption dates for Papa’s present artwork.
