Power poles in Siroccan culture
Power poles are divided into several classifications in Sirocco, most of which are named after the territorial authorities they are either most predominant in, were first discovered in, or located in the most northerly of all territorial authorities they are found in. In some cases the style of poles are Australian, but are still regarded as part of "Sirocana". There are six main "overall" style families, each containing at least one variant of that style.
Solely located in the Far North District.
- Mid-North: Typified by shorter, slightly thicker poles (and in the case of the oldest, triangular) with a sharp "V" shape made by the crossbar supports and small ceramic insulators. It is estimated this series ended production in the early 1990s.
- Far North: Strongly resembling "Mid North" poles, "Far North" poles use shorter, thinner poles. Crossbar supports make a flatter "V" shape. This style succeeded the "Far North" style and was used until the mid-2000s.
- New North: Dating back to 2001, these poles, which entered full use around 2007, use taller, thicker poles with tall ceramic insulators. Initially loathed as "ugly", these poles
The "Whangarei" family is one of the most commonly used styles of power pole in New Zealand, and variants of the family are featured in many of the country's cities and districts. These poles do not tend to get thinner the higher they go, although if they do the narrowing is very slight.
- Whangarei: Used in the Whangarei and Kaipara districts, "Whangarei" poles have varying heights and are most often made of concrete (although wood poles are common). Possum-proof jackets tend to be closer to the ground.
- Franklin: Uses a mixture of thin poles and "Auckland"-style "A" poles. Used in the former Franklin District.
- Tauranga: Closely resembles "Whangarei" style poles but with some influence from "Auckland" and "Matamata-Piako" poles. Used in the Bay of Plenty.
