"It's a disappointment trade," said Weston. Given a dearth of domestic data, Weston said the local market may also be dwelling on its disappointment after last week's pre-election budget update saw lower growth targets and the election uncertainty may also be keeping the kiwi capped.
The trade-weighted index was little changed from 75.86 in Wellington at the end of last week.
The New Zealand dollar was at 91.17 Australian cents from 91.21 cents in New York on Friday and at 56.18 British pence from 56.07 pence. The kiwi traded at 4.8051 yuan from 4.8007 yuan and was at 78.96 yen from 79.10 yen.
The two-year swap rose 2 basis points to 2.18 and Weston expects it to remain range-bound at least in the short to medium term. "It all hinges on when the RBNZ decides, if they decide at all, that they are going to turn to a slightly more hawkish stance," he said. The central bank has signaled interest rates will remain on hold until well into 2019, with a quarter-point increase not fully predicted until March 2020.
The 10-year swap was unchanged at 3.12 per cent Weston said it is just steepening and flattening in line with moves in the US.
