Sione Molia opens the scoring for New Zealand.
12:32pm: Unbelievable brain explosion from Ramos. Scores tied 12-12, Spain hammering the Canadian defence, siren sounds... and Ramos kicks the ball into touch.
Draw. He obviously thought Spain were ahead and is absolutely kicking himself now.

12:23pm: Canada up by just the one try at half-time (5-0) and maybe they should be further ahead, so Spain still with a chance.

Spain and Canada are next - they're in New Zealand's pool and Spain are one of the surprise performers on this year's circuit, beating Scotland in the quarter-finals and finishing sixth at Cape Town. That was just two spots behind NZ.
11:57am: Wow, Fiji are 33-0 at half-time, scoring five tries in the process. The tournament goes up a notch when they take the field, with their combination of speed, skill and power.
Aminiasi Tuimaba has two of those tries.
Meanwhile, good news on the Perry Baker injury, if a little unbelievable...
USA Rugby have tweeted that he's passed his HIA, but will now undergo ex-rays.
He must have an extremely hard head - or a very low HIA baseline.
11:49am: Australia hold on for a 17-12 victory on Australia Day, giving them the inside running on a quarterfinal berth. Skipper Lewis Holland scores a vital try and forces the turnover that cements the win in the final seconds.
Champions Fiji are up next against Wales and they're obvious fan favourites wherever they go. Of course, the Welsh were once world champions, but so long ago now (2009), it's almost irrelevant.
11:40am: The Aussies are up 10-5 at half-time, but this game could still go either way. Fiji and Wales are also in this pool, and the All Blacks Sevens cross over with these teams in knockout play.
You'd think defending champions Fiji would top the group, but the second qualifiers might face New Zealand in the quarters, all things going to plan.
11:29am: Well, the Americans have sounded a warning to their pool rivals, overrunning Tonga 29-7 with three second-half tries, including Tomasin's second.
Scary moment for speedster Perry Baker, who is smashed in a big tackle that involved a head clash. He could be out for the tournament.
The referee yellow-cards Tana Fotofili for the tackle, which he deems high. Baker wobbles off the field.
Australia vs Argentina are next - this has implications on New Zealand, who cross over with this pool in quarter-finals.
11:14am: USA have two quick tries to Carlin Isles and Stephen Tomasin to lead 17-7 before the break.
11:10am: The Americans score first, but John Tapueluelu produces a try that is only surpassed by the quality of his haircut. The side-line conversion gives Tonga a 7-5 lead.
11:01am: England close to 12-10 through a try to Richard de Carpentier, with 30 seconds remaining - but Tom Mitchell misses the conversion. That could be so costly.
Samoa hold on to win. USA vs Tonga next.
10:50am: Elisapeta Alofipo opens the scoring, as Samoa take the initiative over England. Alatasi Tupou scores from the kick-off to stretch their advantage to 12-0, approaching half-time.
10:40am: South Africa run away with victory in the Battle of Africa, heading off Kenya 29-10. Next up is England vs Samoa - this could be a beauty.

10:22am: South Africa vs Kenya is now underway.

Pre-tourament banter: All Blacks Sevens eye revenge against Japan
The All Black Sevens are determined to leave their mark in Hamilton this weekend with talk the leg could alternate with Fiji from next year.
Tim Mikkelson returns to side to lead them on his home track and he's got revenge on his mind first game up
It's the first time Mikkelson will face Japan since the Olympic upset and he doesn't want a repeat performance.
"Japan have got that flare, they off load, they cut, they grubber, they're so unpredictable and that's what makes them so good," said Mikkelson.
But the All Blacks Sevens are championing a melting pot of cultures for their recent success at the World Cup and in Dubai.
Their regular ritual is singing verses from each player's heritage.
"At first the boys were a little hesitant, but after a year of doing it the boys love it eh and every year we add songs and songs.
"It's good, we all come from different backgrounds so we want everyone to bring their side in."
This weekend they're motivated by what will hopefully be their first win at home since 2016.
The side sit second in the World Series standings and a top four finish will automatically qualify them for next year's Tokyo Olympics.
"That's the goal is to win the world series, it's not about finishing fourth for us."
Tim Mikkelson is ready to make his mark on his home ground this weekend.
