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 seems to be in a Columbus 26 'Exeter' style cabinet (complete with Columbus knobs and speaker), but it is unknown if this was how they came from the factory or if this was rehomed at some point (the original Courtenay model 26 and 27 cabinets seem to be particularly attractive to borer and most examples found these days are badly damaged). Given that everything but the dial is branded Columbus, its possible that this is, in fact, a Columbus and 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.

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.
Model codes beginning with a 0, for example the model 051, are Osram valve versions of the model without the leading 0. Technically the 0 should be an O (for Osram), however the digit 0 was used throughout the site before this fact was discovered.
The E suffix indicates a magic eye option is fitted (in models which were available with or without, such as the model 25).
A and B suffixes appear to be simply updates to the current model, R also appears to be simply an updated model ('R'edesign, perhaps?)
P indicates either a permanent magnet speaker version of a model which also came with an electromagnet speaker (the model 26 for example), or a portable model (like the model 694P).
N and M indicated miniature valve versions of a model which started with all (or a mix, ie: model 5) of larger valves. One of these two codes may indicate a transitional mixture of octal and miniature - clarification is required.
S often indicates a stereo model.
Finally, other suffixes and prefixes make occasional appearances in the RCNZ lineup - like the 66W (a variant of the long-running model 66) and the 75XA (a 10-valve version of the model 75 with a separate amplifier chassis).
