Investors' expectations for future US rate hikes dimmed this week after minutes to the Federal Reserve's last policy meeting showed little desire to tighten.
That has left New Zealand an attractive place for international investors with an economy enjoying booming tourism and building activity and a Reserve Bank yet to exhaust conventional monetary policy.
The yield on New Zealand's 10-year government bonds at 2.23 per cent remains more attractive than Australia's equivalent government bond, which was recently at a yield of 1.93 per cent, and US 10-year Treasuries' yield of 1.55 per cent.
"The kiwi is still at elevated levels and the Reserve Bank still won't like it, but until they lower rates is going to stay attractive," said Michael Johnston, senior trader at HiFX in Auckland."
