England are struggling to avoid the follow-on against New Zealand after losing three wickets before lunch on day three of the third Test in Auckland.
The tourists began the morning on 50-2 but lost Nick Compton early to a delivery from Tim Southee after a lengthy appeal.
With both sides unsure, the Hawkeye system showed the verdict of lbw was justified.
Southee quickly claimed a second wicket as Ian Bell was punished for a lack of movement by a swinging delivery that came back off his pads.
Jonny Bairstow fared little better and was also out 30 minutes later for just three runs, thanks to an expert use of the review system by Black Caps skipper Brendon McCullum.
Joe Root and Matt Prior came in to steady the ship as England reached 92-5 at lunch, still needing to reach a total of 244 runs to avoid batting again.
