Christchurch: New Zealand had the scent of victory after only the second day of the first Test against Sri Lanka Saturday after a scintillating bowling spell forced the tourists to follow on 303 runs in arrears.

After New Zealand posted 441 in their first innings at Hagley Oval in Christchurch, a four-pronged pace attack led by Trent Boult dismissed Sri Lanka for 138 inside 43 overs.
