England and New Zealand kicked off the 2013 Test match summer with a hard fought affair - the hosts reaching 160/4 in 80 overs, before rain ended play early.
Full scorecard & as it happened
Here's Lords.org's picks from day one.
Dean Brownlie's catch to dismiss Jonathan Trott was a stunning bit of fielding.
The ball would not have carried to second slip, so Brownlie dived low to his left from third to take the catch at boot height.
The delivery from Trent Boult wasn't half bad either and combined to produce the best cricket of the day.
Man of the day
Perhaps not a Boult from the blue after his winter efforts, but figures of 2 for 29 off 17 overs was just reward for the 23-year-old.
He bowled consistently all day and always looked a threat with late swing.
Alastair Cook in particular was all at sea against the left-armer, scoring just two runs off 35 deliveries from Boult, before the Black Caps man finally removed the England skipper.
Expect that to be a battle which holds a big sway over the result of this series.
Photo of the day
It's only fitting that our picture of the day, from MCC's resident photographer at Lord's Matt Bright, should be of the best player on display.
Trent Boult bowled with a spring in his step throughout the opening day, and his joy at getting the wicket of Alastair Cook is perfectly captured in this picture.
Circumspect. England had periods where they subdued the excellent New Zealand attack, but their batting never really got out of second gear.
There was a lack of fluency in their batting which led to a cautious aproach and a run rate which hovered around the two runs-per-over mark.
The day tomorrow
England will be flying the White Rose tonight, with their hopes resting on the in-form Yorkshire youngsters, Joe Root and Jonny Bairstow.
Root looked calm on his way to 25, while Bairstow made his highest Test score so far (95) at this Ground against South Africa last year.
New Zealand will have a new cherry available from the first ball, so Root's skills as an opener will come under scrutiny if the likes of Boult and Tim Southee bowl as they did on day one.
Oh, and there's also England's best player of 2012/13, Matt Prior, to come as well.
