Former Otago seamer Nathan Smith recorded the fastest six-wicket haul by a New Zealander as the Black Caps took control of the one-off test against Ireland in Belfast.
Tom Blundell scored a career-best 186 and Dean Foxcroft fell just short of a century on debut, making 98, to help New Zealand to 490/8 before captain Tom Latham declared.
The Black Caps then rolled the hosts for 179 in their first innings before enforcing the follow-on, with Ireland reaching 65/2 at stumps on day two at Stormont, trailing by 246 runs.
The visitors are now eight wickets away from winning the four-day test, which precedes a three-test series in England.
Paceman Smith ended with a career-best figures of 6-40 and took just 29 balls to complete his five-wicket haul, breaking Shane Bond's record of 39 as the fastest by a New Zealander.
Smith swung the new ball and caused Ireland's top order all sorts of problems. He was helped by fellow pace bowlers Ben Sears, who took two wickets, and Blair Tickner and Zak Foulkes, who took one each.
Tickner took the two Ireland wickets in their second innings.
"You probably saw that it was hardest to bat with the new ball when it was a little bit harder. But Smudger (Smith) showed pretty much exactly where he needed to bowl with the new ball. He's got experience with the Duke and he showed that.
"It was pretty impressive to watch and it was awesome to be a part of that. Hopefully we can have a little bit more in the morning."
Tickner said he was pleased the Black Caps made Ireland bat again.
"I wasn't privy to the conversation, but I was keen to keep bowling because I needed to bowl more," Tickner said.
"I was keen to get more time on the legs and it's good for the bowlers to do that. We haven't had much cricket, especially red-ball cricket. So it was very enjoyable to keep going."
Tickner said the Black Caps' bowlers hope to get a bit more out of the pitch on day three as they chase the eight wickets they need to win the match.
"It's a very dry surface, so we're hoping a little bit more up and down bounce for us tomorrow and then hopefully we can keep taking poles."
Day three starts at 10pm on Friday (NZT).
