Venus's elevation meant ASB Classic tournament director Karl Budge was able to take one wildcard back and reward Daniell (50) and Sitak (62) for their solid years on tour.
"It's incredibly rare to have three doubles combinations that New Zealand fans can get behind in the main draw and they're all genuine title contenders," said Budge.
"New Zealand doubles has really come into its own in 2016 with Venus, Daniell and Sitak flying the flag on tour. We're lucky that the cards have fallen so that we can have them all in the main draw and with the opportunity to play with their usual partners,"
Sitak has been playing with American Nicholas Monroe and Daniell with Brazilian Marcelo Demoliner.
Venus has enjoyed his best year on the ATP Tour capturing four doubles titles and reaching a further five finals.
The 29-year-old's formidable year was punctuated with titles in Auckland, Montpellier, Marseille and 's-Hertogenbosch.
One of the best memories was his run to the Auckland title alongside Pavic, where the duo didn't drop a set across the entire week.
Venus also reached the doubles semi-finals in 2012.
