"They're world leaders in most forms of the game so it's fantastic to take them on," Canterbury allrounder Ellis said yesterday.
"Every game you play domestically, or for a New Zealand XI, is an opportunity to push your claims and most people should have enough professional pride that they're putting their best foot forward."
Taylor's importance to the New Zealand batting operation means most scrutiny will be on him today.
"It's always a bonus to have Roscoe around," Ellis said. "He's world class, he's got a smile on his face and hopefully we see a few trademark slog sweeps over the ropes."
England's tourists are keen to get into action, appreciating the worth of the next two games.
"They're very important to get our basics going, get the team nice and gelled together," opener Alex Hales said.
Hales made a significant statement when he arrived to join the Melbourne Renegades in Australia's Big Bash last month. The tall, free-hitting opener clobbered 89 off 52 balls against the hapless Sydney Sixers.
Ellis hadn't seen the innings but quipped, "I've heard he goes all right," adding, "but he's just one of many we'll be looking to target."
England's T20 captain Stuart Broad, who has battled a heel problem, is keen to stretch out. His buildup was compounded by England's dreadful weather limiting training opportunities before coming to New Zealand. He had not bowled outdoors since leaving the tour of India six weeks ago until getting to Auckland.
"We have two weeks solid of T20 cricket and it's going to be a battle," he said.
"It's a long tour for us but we have to break it down into small parts to be successful."
Just as Ellis and co have a team focus as well.
"We have to see ourselves as possibly spoilers for the start of the tour," Ellis said. "It would be fantastic to put them on the back foot and for the Black Caps to take some momentum from that."
