There was a gap of 2-1/4 lengths back to third placed Zeefa Zed.
Call Me Jack returned a dividend of $31.10 for a win and $8.50 for a place, while the quinella with the well supported Tiro paid $102.30.
Symes was pleasantly surprised by Call Me Jack's form reversal, saying that track conditions on the day proved a deciding factor.
"He's a horse that needs rain on the day to make it loose and that's exactly what he got at Hawera," Symes said.
"The track was a bit too good for him at Hastings the start before."
Call Me Jack was recording his second win from 14 starts. The first was in a 1600m maiden highweight on a heavy track at Wanganui in June last year where he also returned outside odds of 18-to-one.
He is raced by Symes and his son Wilfred and they bred him out of the Stark South mare Gizakis.
The latter showed nothing in four starts on the racetrack but is a daughter of Love Proposal, a Spectacular Love mare who had two wins and seven minor placings from 41 starts.
Love Proposal was also the dam of The Veep, whose 10 wins included the 2008 Group 2 Hawke's Bay Cup (2200m).
The Symes also have an unraced 2-year-old full-brother to Call Me Jack coming on but the mare is not in foal at the moment.
The sire Jakkalberry, who is now deceased, was placed third behind Green Moon and Fiorente in the 2012 Melbourne Cup.
Record nominees for HB features
Hawke's Bay Racing has received record nominations for all three Group 1 races at this year's Bostock New Zealand Hawke's Bay spring carnival but several of last season's star performers are likely to miss the carnival.
The three feature weight-for-age events are the $200,000 Tarzino Trophy (1400m) on September 19, the $200,000 Windsor Park Plate (1600m) on October 3 and the $250,000 Livamol Classic (2040m) on October 17.
There are 52 horses nominated for the Tarzino Trophy including last season's champion three-year-old filly Jennifer Eccles and multiple Group 1 winner Avantage.
The pair are also among 67 nominations for the Windsor Park Plate and the 86 nominees for the Livamol Classic.
Cambridge trainer Shaun Ritchie has already earmarked Jennifer Eccles for all three races at Hastings while Avantage's trainer Jamie Richards said the Fastnet Rock mare will probably contest at least two of them.
Jennifer Eccles has not raced since winning the Group 1 New Zealand Oaks (2400m) at Trentham in March and that followed a hollow victory in the Group 2 Lowland Stakes (2100m) at Hastings. She finished a close up fourth in a 1050m Ruakaka trial on August 4 and Ritchie is extremely happy with the way she is coming up.
Jamie Richards was also pleased with Avantage's win in an 1100m Taupo trial on Wednesday and said she is coming up really well again.
Avantage was ridden by Opie Bosson in the trial. She settled midfield before improving four-wide coming to the home turn and took control soon after Bosson didn't really ask her to extend at any stage and she went on to score a comfortable neck win over fellow Tarzino Trophy nominee Supera.
"She (Avantage) will run in the Foxbridge Plate at Te Rapa on September 5 and then the first couple of legs at Hastings," Richards said.
"We have got a little bit of time to fill between now and then, but she is coming up really nicely and we are pleased with where she is at."
Among the other star gallopers nominated for the three Hawke's Bay Group 1 features are Bostonian, Catalyst, The Chosen One and Quick Thinker but all four are expected to do their spring racing in Australia.
Bostonian is booked on a flight to Sydney on Monday and will resume in the Group 1 Winx Stakes (1400m) at Randwick next Saturday.
Two of Pike's stable staff, Chris McNab and Matthew Ward, were granted travel exemptions to enter Australia and were on a flight to Sydney yesterday. They will need to go into quarantine for two weeks over there so Bostonian will be put in the temporary care of former New Zealand trainer Bjorn Baker for his first up run.
Pike may have another couple of his stable runners heading to Sydney if they perform well in trials in the coming weeks while his team across the Tasman will receive a major boost with the addition of Catalyst next month.
Trainer Clayton Chipperfield is unable to head to Sydney so Pike and his staff will take charge of Catalyst, who was super-impressive when winning his 1100m Taupo trial on Wednesday.
The Darci Brahma 4-year-old is booked on a flight to Sydney on September 14 and is expected to make a return to the racetrack in the Group 2 The Shorts (1100m) at Randwick five days later.
Chipperfield was delighted with Catalyst's Taupo trial, where the gelding cruised to a 1-3/4 length win over Aretha and Sherrif and said the horse will improve a lot from the trial.
"He's a lot stronger in his action and he's mentally stronger as well," Chipperfield said.
"Depending on how he progresses we may trial him again or we will find a race meeting and give him an exhibition gallop before he flies out."
The TAB has released Fixed Odds win markets for the three Hawke's Bay Group 1 races.
The Tarzino Trophy market still has Bostonian and Catalyst included with Avantage the favourite at $4.00. Bostonian, Catalyst and Travelling Light are on the next line of betting at $6.50; Supera ($8.00); Julius and Kiwi Ida ($10); Prise De Fer ($12); Two Illicit ($14); True Enough ($16), Dragon Leap and Scott Base ($18), Jennifer Eccles ($21) and Germanicus, Princess Kereru and The Mitigator ($26). All other horses are at a quote of $30 or more.
