"Maybe there'll be no respite for the kiwi until a positive dairy auction next week, but it's a US dollar story, and when you look at the long-dated charts for the dollar index, this move could only just be the beginning."
New Zealand's two-year swap rate rose 2 basis points to 2.29 per cent and 10-year swaps gained 3 basis points to 3.3 per cent.
