From Jacks Stream

The summits of the Kaimakamaka Peaks are easily visible from Twizel to the north of Mackenzies Peak. From Jacks Stream, take the obvious spur beside the first major subsidiary stream, climb past the tarn and then up the east ridge to Pk 2392m. From here, it’s an easy traverse to Pk 2431m. Alternatively, from upper Jacks Stream, ascend the north-facing scree directly to the high peak.
