While disappointing to see the local competition look so despairingly out of their depth, the results were to be expected when you consider the experience they were up against. Venus, who has an ATP ranking of 399, said he was realistic that he needed to be at his absolute best to challenge Lacko (90).
"I didn't play well today. That's why he's a top 100 player - he took care of business pretty quickly," said Venus.
"It's disappointing because you don't get to play [tournaments in NZ] much so when you do you want to play well. Maybe I had too many expectations on myself, maybe I should aim to go out there and enjoy myself and just have fun."
Venus will still feature in the main draw of the doubles this week, pairing up with Statham as he prepares for next week's Australian Open.
The 26-year-old Kiwi said he was confident he and Statham could give the local crowd something to cheer about in the doubles. "I feel completely comfortable with these guys in the doubles ... so I'm really looking forward to getting out there again."
With the top four seeds handed a first-round bye, the day delivered little in the way of top-flight action.
Columbia's Santiago Giraldo was the first player to win his way through to the second round, defeating Spain's Albert Montanes, a player ranked seven spots above him, 6-1, 7-6(3) and American Jack Sock beat France's Adrian Mannarino 6-3, 6-4.
Two seeds will be in action today, Germany's Philipp Kohlschreiber (playing Spaniard Pablo Carreno Busta) and fifth seed Benoit Paire of France against Poland's Michal Przysiezny.
