Zimbabwe were bowled out for 51 in their first innings, and were in danger of repeating the dose second time around after falling to 12-5 after 10 overs. But a half century from Regis Chakabva, who combined with Graeme Cremer to forge a 63-run partnership for the seventh wicket, at least gave some respectability to Zimbabwe's second innings.
It looked as if Zimbabwe had managed to force the match into a fourth day, but the return of Martin to the bowling crease saw the last three wickets fall for four runs and saw the visitors dismissed for 143.
Martin and Doug Bracewell were the chief destroyers with the ball for New Zealand, as both seamers took two wickets in Zimbabwe's first innings, before veteran's haul was complemented by three from the youngster in the second innings.
Earlier, the Black Caps declared at 495-7 once BJ Watling had brought up his maiden test century. After the declaration came with Watling unbeaten on 102, New Zealand immediately had Zimbabwe in trouble as Martin (2-5), Trent Boult (2-8) and Bracewell (1-7) picked up wickets with ease to have Zimbabwe reeling on 20-5 at lunch.
The wickets continued to tumble after the break, with Malcolm Waller (23) the only Zimbabwean batsman to reach double figures. New Zealand enforced the follow-on with Zimbabwe still trailing by 444 runs, and the tourists were quickly in trouble again.
Martin struck in each of his first three overs, as opening bat Hamilton Masakadza registered a rare one-day pair and captain Brendon Taylor managed a combined 11 runs. Chakabva frustrated the New Zealand attack for a time but Martin eventually wrapped up the tail.
