What to Consider When Choosing
1. Performance Track Record
Look at 5-year and 10-year returns, not just recent performance. Consistent returns matter more than occasional spikes.
2. Fees and Charges
Even 0.5% difference in fees can cost $50,000+ over a career. Prioritize low-fee providers when performance is similar.
3. Investment Philosophy
Active vs passive management, ethical screening, NZ vs global focus—choose what aligns with your values.
4. Fund Options
Ensure they offer the fund type you need (conservative, balanced, growth) and allow easy switching.
5. Technology & Service
Modern app, online account access, responsive customer service, and clear reporting matter for long-term satisfaction.
