RBNZ's New Zealand CPI Inflation Calculator

The Reserve Bank of New Zealand has created a way you can easily work out what something which, for example, your grandparents bought for 2 pounds back in 1935 would cost today. It's "The New Zealand CPI Inflation Calculator". A quick check showed something costing (before introduction of NZ $) £1 in 1919 would cost $75 now.
