Horticulture Sector Backs Government's RSE Scheme Overhaul
There's strong support from the horticulture sector for the Government's plans to overhaul and streamline the Recognised Seasonal Employer (RSE) scheme.
Instead, New Zealand received only a modest tremor: a letter from Climate Change Minister Simon Watts to regional and district councils. It politely draws attention to the issue and "expects" councils to review their climate assumptions. This low-key response falls short of what is needed.
The background matters. In 2014 the IPCC developed four Representative Concentration Pathways (RCPs): RCP2.6, RCP4.5, RCP6.0 and RCP8.5. In its Sixth Assessment Report (AR6, 2021), it updated these into Shared Socioeconomic Pathways (SSPs). The key scenarios include SSP1-2.6, SSP2-4.5 and SSP5-8.5.
The low-numbered pathway assumes strong global action and attaining net zero. The high-numbered one projects explosive emissions growth, including burning more coal than known reserves. The world's actual trajectory sits closer to the lower-to-intermediate range - nowhere near the extremes of the 8.5 pathways.
Crucially, the 8.5 scenarios were never intended as likely futures or "business as usual". They were designed as high-end stress tests. Yet they have repeatedly been treated as the default in modelling. This shows up across New Zealand: in Kapiti Coast planning, where thousands of properties face exaggerated sea-level rise risks; in projections of the sea lapping at Parliament's steps by 2100; and in agricultural policy. The New Zealand Agricultural Greenhous Gas Research Centre and programmes like AgriZero rely on RCP8.5 assumptions to justify major methane reduction targets and spending.
This pattern repeats in councils and government agencies nationwide. When extreme scenarios drive policy, the result is often over-regulation, inflated infrastructure costs, and misallocated resources.
Contrast this with Minister Erica Stanford's decisive action on an MBIE project plagued by cost overruns and zero results. She pulled the plug. Minister Watts and the government should show similar resolve. Rather than layering on new spending - such as the $51 million Early Adoption Accelerator for methane vaccines and boluses - they should direct a full reset: redraw all climate policies and planning using realistic, evidence-based scenarios grounded in measurable data and current trajectories.
New Zealand has faced severe weather events in recent years. Yet the IPCC itself notes limited evidence for detecting and attributing a clear human influence on many of these specific events in our region. Despite this, public discourse often defaults to alarm, amplified by models built on discredited high-end assumptions. It is no wonder many Kiwis believe cattle burps and V8 engines are the primary culprits.
A country grappling with economic pressures cannot afford billions on policies anchored in implausible scenarios that deliver no measurable global benefit. The responsible path forward is clear: prioritise robust adaptation to the climate variability we have always faced, informed by the best available science and probable futures - not worst-case fantasies. This approach has sustained humanity for millennia and remains far more cost-effective than chasing symbolic reductions with negligible real-world impact.
New Zealand's policies must reflect reality, not outdated modelling. The data demands it. Our economy and communities deserve no less.
