Tim Southee may have rescued the New Zealand cricketers on day one of the second Test against Sri Lanka, but more is needed on day two.
Southee top scored with 68 and then took three wickets.
Sri Lanka will start day two on 88 for four in reply to the Black Caps 178.
Southee says they probably have to be happy with day one after being asked to bat first on a green Hagley Oval wicket.
"Fairly even, would have been nice to have grabbed one more tonight."
"But we knew that if we could somehow get through to 200 after losing the toss on that wicket and try and put a score on the board and then if you can take a few quick wickets and then hopefully you can gain some momentum and I guess the first session tomorrow (Thursday) it'll be important for both teams.
Southee counter-attacked with wicketkeeper BJ Watling to blast 68 from 65 balls and take New Zealand from the depths of despair on 64 for 6 after Suranga Lakmal had destroyed the top order on a green wicket.
The 30-year-old Southee and Watling (46) combined for 108-runs as New Zealand were dismissed for 178 with Lakmal finishing with five for 54.
First test centurion Angelo Mathews was on 27 with Roshen Silva (15) as the visitors were 4-88 at stumps on Wednesday, with neither team holding the advantage as both seek to win the two-match series with victory in Christchurch.
The first test in Wellington ended last week in a damp draw after virtually all of the final day's play was washed out.
The 31-year-old Lakmal, utilising the overcast, cool conditions and green pitch, had reduced the hosts to 4-36 after Dinesh Chandimal had won the toss and wasted little time in choosing to field.
Lakmal went to lunch having bowled 12 successive overs with figures of four for 18.
Southee, whose innings of 77 not out in his debut in 2008 remains his highest score, then decided attack was the best form of defence and belted six fours and three sixes to resurrect his side's fortunes.
His dismissal, to a brilliant, one-handed leaping catch by Danushka Gunathilaka at short mid-wicket, sparked another collapse with the last three wickets adding just six runs.
Southee then took the first three Sri Lankan wickets to reduce them to 21 for 3 inside 10 overs.
The second victim - Chandimal for six - moved him to 234 test wickets and third on New Zealand's all-time list.
Chris Martin had been in third on 233, although Southee is still a long way away from Daniel Vettori's 361 and Richard Hadlee's New Zealand-leading mark of 431 wickets.
After his initial spell, Southee continued to be a threat towards the end of the day's play as Silva and Mathews played and missed several times but saw their side through to stumps.
