"We've scored the most tries in the comp and we've got the best defence in the comp, but we're not playing for the top four. It's been a tough couple of days, but now we've got a chance to make a wee statement."
That chance comes against a Wales side who have proved themselves as tough opponents throughout the competition, with every one of their games decided by just a single point margin.
"Wales are a team that comes outside in on defence," added Robertson. "They bring a lot of line speed and they disrupt you around the breakdown. Against us they never passed the ball more than twice in a row the whole game. They try and stop you playing rugby, so for us our challenge is to firstly create the opportunities and then convert them. We're going to play: that's our mindset, that's our skillset."
Despite the disappointment of playing off for fifth position and not the championship itself, the head coach has seen some real quality in many of his young players, especially in the backline.
"I've been impressed with Stephen Perofeta at 10. I think he's done a great job with his kicking game, especially in the wet and his execution's been really strong. A lot of our bench guys are young boys who've come on and made a really good impact. Obviously Jordie Barrett's been exceptional. His courage and his skill level have been so high and he's a great young man.
"Our outside backs are a real strength. We want to play with width and get the ball out there, but we haven't given those guys much opportunity. When we have, Shaun Stevenson has been critical with his line breaks, metres gained and men beaten which have been as good as anyone in the comp. Jonah Lowe is just a tough, relentless outside back and Caleb Makene can play on the wing or at fullback and he's safe as."
Wales have made four changes, some injury-enforced.
Their coach Jason Strange believes playing New Zealand twice within a week is just the sort of challenge the players need.
"These are the high intensity matches the players require to accelerate their development and we're really pleased with their progress so far. The players were excellent on (Thursday). Despite the loss, you couldn't fault their collective effort and level of performance. The match was decided on a few critical decisions and hopefully we have learned from those high pressure situations.
"The players have had a lot of success this season, however it's also important to go through this process of losing and learning from your mistakes. It will be interesting to see how both teams approach the game tactically after the last match. We will attempt to continue playing the game with skill and passion," Strange said.
Kickoff is at 2.15am (NZT) tomorrow.
