They will join other visitors from as far afield as Taupo, Palmerston North and Rotorua, along with locals, for what will be the largest festival staged yet.
Since it was first sparked up back in the summer of 2015, it has grown in both the way it provides a great wine sipping, food savouring and musical entertainment day out, as well as how many people it attracts.
"Every year there has been an increase of hundreds more tickets but we're looking to cap it now around the 2500 mark," Mr Ham said.
The inaugural festival saw the 1000 tickets on offer quickly snapped up, and in the wake of that Mr Ham said "we will now raise the bar".
And they indeed have through the years, to the stage where it is now a highly acclaimed and anticipated part of the Bay's hospitality, entertainment and tourism calendar.
"We have looked at our preparations from the first year through to now and changed quite a lot, and we are geared up now for bigger crowds," Mr Ham said.
"We are very happy with the way it has developed."
The wineries set to roll out the welcome mat are Abbey Estate, Alpha Domus, Ash Ridge, Ngatarawa, Oak Estate, Paritua, Red Metal and Sileni, and each will be teaming up with a local chef or restaurant to offer a variety of dishes to visitors, alongside their finest wines.
They will also stage live musical flavours.
"The Bridge Pa Triangle Wine District is made up of dedicated and passionate winegrowers and we are proud to showcase our vineyards and our wines as part of the festival," Mr Ham said.
As in past years, festival buses will be running from specific locations in Napier (i-Site Centre), Hastings (Russell St Sth cenotaph), Taradale (Lee Rd bus stop) and Havelock North (i-Site).
The first buses will leave at 9.45am and depart when full, as will the following buses until the final departures at 11.15am.
After being let off at one of the wineries festival-goers can then later head for others aboard shuttles which will be operating, with the buses beginning the return runs back to town from 4.30pm.
Bus and general admission tickets are $55 while admission only is $38.
"It is the variety people can get in that one day that makes this so special," Mr Ham said.
While the organisers recommended using the bus services ticket holders could travel by car, but a designated driver was insisted upon.
"There are a few tickets left," Mr Ham said yesterday afternoon.
"But they are going fast."
Just as it is to the creation of a fine vintage, the weather is always an important factor when it comes to staging a celebration of one of the Bay's, and New Zealand's, unique wine regions.
And despite the forecast for some showers on Thursday and Friday at this stage Saturday is looking pretty good, with WeatherWatch forecasting a partly cloudy day with a potential high of 27C.
"We are keeping a close eye on the weather and it's looking pretty good at this stage," Mr Ham said.
"But rain or shine — it will still go ahead."
