Essential Tips

What to Pack

Quick-dry rain jacket (not umbrella) - afternoon showers last 45-90 minutes with frequent winds making umbrellas useless

SPF 50+ reef-safe sunscreen - UV index reaches 8 even on cloudy days and reapplication needed every 90 minutes

Moisture-wicking shirts (avoid cotton) - 70% humidity makes cotton uncomfortable and slow to dry

Waterproof phone case - essential for lagoon activities and unexpected rain, plus sand protection

Closed-toe water shoes with grip - volcanic rocks and coral require protection, flip-flops insufficient for most activities

Lightweight long pants for mosquito protection - dawn and dusk require coverage, DEET alone insufficient

Portable power bank - charging infrastructure limited on outer islands and boat tours run 6-8 hours

Cash in small bills (NZ$10-20 notes) - many local vendors and markets don't accept cards or provide change for large bills

Snorkeling gear if experienced - rental gear often poor quality, bringing own mask ensures proper fit and comfort

Insider Knowledge

Local buses (NZ$5 around Rarotonga) run every 30 minutes clockwise/counterclockwise - locals board anticlockwise for shorter journeys, tourists always go clockwise

Saturday morning Punanga Nui Market (6am-12pm) offers best local produce prices and freshest selection - arrive before 8am for traditional breakfast foods

Mobile data is expensive (NZ$30+ for 5GB) but most accommodations offer good WiFi - download offline maps and entertainment before arriving

April's afternoon rains create flash flooding on some coastal roads - locals know alternative routes through plantations, ask accommodation for backup driving directions
