"And it's another excuse for us to ham it up a little and have a good time."
Senior believes the concept of play is important for many reasons.
"Play is an important part of tamariki development. It's out there to give them an opportunity to grow and explore different ideas.
"It's an opportunity to explore their environment - it gives them an opportunity to take something and problem-solve. They can create their own rules.
"Generally, the most important thing with play is that it's fun, and so it means it's the easiest way to be active."
He said this year, the idea was about bridging the gap between the generations and encouraging big kids to get stuck in.
"This year's message for Play Week is, 'Come out and play', and that is Sport NZ's main thing. It's not just for tamariki to play. It's those parents; it's for those other people in the community to come out and play, as well.
"So get involved. It's not just a thing for kids."
As is obvious in the Local Focus video, the team enjoyed their lunchtime showdown. And they are keen to spread the word that playtime should be a regular fixture.
"Play's not limited to just one week. You should be out there every week with your tamariki having a bit of a run-around, going and climbing that tree, or going and building a fort in your house, or going and throwing a frisbee around, or putting on some music and having a boogie and just acting like somebody who's just lost their mind.
"There's lots of fun to be had."
