SYDNEY (Reuters) -Lock Tupou Vaa'i scored a hat-trick of tries as the Waikato Chiefs locked up top spot in the Super Rugby Pacific standings and home advantage throughout the playoffs with a 41-21 victory over the Otago Highlanders on Friday.
Runners-up for the last two years, the Chiefs did not hit the heights they have this year in their final regular season clash but always looked like having enough to get past a young Highlanders side.
