Darren Bravo provided stubborn resistance to New Zealand's bowlers bringing up his maiden test double century to ensure West Indies made the hosts bat again and sent the first test at University Oval in Dunedin into a fifth and final day.
Bravo, whose previous best test score was 195 against Bangladesh in 2011, ended the fourth day on Friday 210 not out after he had guided the visitors to 443 for six in their second innings, a lead of 47 runs. He had batted for almost 10 hours.
The hosts are still strongly favoured to win the match, though periods of rain forecast for Dunedin later on Saturday means they must take the final four West Indies wickets early to ensure a first test victory in more than a year.
West Indies captain Darren Sammy, still hampered by a hamstring injury he sustained while bowling, was unbeaten on 44 after he and Bravo had put on a quick-fire 80-run partnership.
