In 2012, Meridian Energy sought to change the conditions controlling Lake Pukaki's water levels and flows. In the event of an energy crisis, the objective was to allow a further five meters to be drawn from the minimum lake level of 518 meters above sea level (masl).

For the proposed changes, r+m prepared a landscape and visual assessment. Their assessment considered the lake and its surrounding setting's existing natural character, landscape, and visual amenity values. r+m referenced relevant plans and landscape studies, taking into account the nature and scale of the proposed drawdown.

r+m's assessment of the effects of increased drawdown on landscape and amenity values contributed to Environment Canterbury granting consent to the changes.
