No NZ new cars prior to unleaded had cats.

Nope. Non-cat/O2 cars had a different ECU. Not hard to change in mass
Interestingly, the Motronic ECU on my Alfa is the same in cat/non-cat
cars. Connect an O2 sensor to one ECU pin, earth another pin and it now
uses closed loop mode (ie. uses the O2 sensor with different maps). It
also has selectable 91/95/98 octane and an alarm function where
grounding one pin refuses to let the engine start.
All cool features for the 80's.
