Circle Pacific fares are only available as 22,000, 26,000 and 29,000 miles variants. The 34,000 mile option is for he Global Explorer fare. To include South America, you must have the xCIR29SA fare type. If including South America, you must travel between Chile and SW Pacific (NZ/Australia) as your south Pacific crossing.

On the 29,000 mile fare, you get 6 free stopovers included, and only one at any one point, and a max of two in any one region (continent really). A surface segment is considered a stopover. You may purchase up to two additional stopovers per region.

Note also that travel on a Circle Pacific fare must be in a generally continuous clockwise or anti-clockwise direction. Backtracking in direction is only permitted where required through certain hub locations

With the Circle Pacific fares, as with moist fares, you are allowed to exercise the "thow-away ticketing" practice of not completing the journey. But the cancellation rule that applies here states the condition of "certified death of the passenger/member of the passenger's immediate family", so that may not be quite such a pleasent manner in which to complete your journey.
