Dawn Carey, from the Brecon Beacons in Wales, is also on a six-week package tour.
She had seen Maori welcomes before but only on TV.
"It was absolutely fabulous, just awe-inspiring. You could actually feel it," she said. "Everyone was so disciplined, so in the moment."
As for the Lions' underwhelming win in Whangarei on Saturday night, she said there was "room for improvement".

"I think they're a bit jet-lagged. Hopefully they'll lift their game and gel together more as a team."
Mr Humphreys was also looking forward to seeing Christchurch again, a city he had visited often to compete in wheelchair tennis championships. It would be his first visit since the earthquakes.
