• Kauri dieback (Phytophthora agathidicida) is the headline forest-health story — climate change does not directly cause it, but warmer winters expand its overwintering window.
• Possum + deer + goat browsing pressure compounds with any climate stress on regenerating native species; mountain rata + native mistletoes are most vulnerable.
• Garden-relevant: New Zealand natives (Hebe, Phormium, Pittosporum, Coprosma, Olearia, Cordyline) ship globally and remain core warm-temperate garden plants; provenance matters strongly for cold-hardiness even within a single species.
