The New Zealand dollar was set to end the week 0.4 per cent lower against the greenback amid growing concerns US President Donald Trump won't be able to push through his pro-business agenda, and in the wake of the attack in Barcelona.
The kiwi was at US72.95c at 5pm today, from US72.86c at 8am and US73.28c on Thursday.
It traded at US73.18c last Friday in New York.
The trade-weighted index declined to 76.93 from 77.13 on Thursday.
"Generally, it's risk off. There are a couple of underlying currents. There's Trump uncertainty and the Barcelona story," said CMC Markets trader Sheldon Slabbert.
