Sustainability upgrades deliver tangible gains for commercial property investors

PMG owns and manages 50 properties nationwide and began measuring portfolio-wide emissions in 2021. Their FY25 Sustainability Report shows that targeted improvements – from solar panels to AI-powered building management – are not only reducing environmental impact but also enhancing property values, tenant satisfaction and retention.

One example is a five-level Christchurch office building where an Intelligent Maintenance system was introduced – the first of its kind in New Zealand for a multi-tenanted property. The AI-driven approach cut energy waste by more than 76,000kWh, reduced carbon emissions by 73.5 tonnes and delivered nearly $12,000 in energy cost savings.

Across the wider portfolio, the installation of EV chargers in partnership with ChargeNet and Hikatron has saved a further 80,000kg of CO₂, while a waste diversion programme with Reclaim has kept more than 40% of waste out of landfill. Their solar partnership with Sunergise is also delivering results, with two Auckland childcare centres achieving a 35% reduction in energy costs since 2023.

PMG’s Head of Facilities and Sustainability, Simi Mukherjee, says the evidence shows that environmental and financial performance are increasingly intertwined.
