The final update to the 26 series, the now obsolete electomagnetic speaker was replaced with a permanent magnet version (hence the 'P' code).
The photographed version appears to be a Columbus although the dial glass is from the Courtenay model. It is assumed the original dial glass was broken and replaced with a Courtenay one which might have been all that was available at the time. However, aside from the cabinet, the dial glass and the transfer on the back of the speaker, the Columbus and Courtenay models were identical.

Chassis Notes(most schematics can be clicked to download a full size version) Uses miniature valves (the 'N' designation is in keeping with RCNZ sets around this era that used them). Has gram input from factory.
General Construction Notes for Radio Corporation of New Zealand Ltd: The first digit of the serial number typically indicates the year of manufacture of RCNZ chassis' (although not the decade - that requires a little knowledge of the valves, construction, etc). Sets from around 1934 onwards were often (but not always) constructed in a distinctive pressed 'baking pan' style chassis, seemingly unique to RCNZ.
