New Zealand should increase KiwiSaver contributions and expand its coverage to improve the country's retirement income system, according to a global study.
The Melbourne Mercer Global Pension Index, which benchmarks retirement income systems around the world, included New Zealand for the first time this year giving it a "B" rating.
Although that might seem like an average result, no country received an A rating overall for its pension system.
The top-ranked country was Denmark, followed by the Netherlands and Australia which all received a B+.
New Zealand ranked 9th behind Norway, Finland and Sweden, Singapore and Switzerland.
