Economists expect a quarterly inflation rate of 0.7 per cent for a 2 per cent increase from a year earlier. Stronger inflation may see the kiwi fall against the Aussie dollar, Rudings said.
The kiwi fell last week after unexpectedly weak New Zealand inflation.
Longer term, the interest rate differential between the US and New Zealand is likely to be a key driver of the kiwi. If the Fed hikes through this year and the differential becomes clearly in the greenback's favour, "the US dollar will be racing. It might even be the new carry trade," Rudings said.
Trump's speech to the Congress, titled "Building a safe, strong and proud America" is due out tomorrow morning New Zealand time. He is expected to set out his priorities for jobs, infrastructure, immigration, trade and national security.
Trump has yet to detail his US$1.7 trillion ($2.3t) election pledge to invest in US infrastructure projects but that type of spending would likely have a more direct impact on US economic growth than his tax reform package and help underpin a US dollar index hovering near a four-year low.
