There were 50 people in the Association of Sri Lankans in Hawkes Bay and about 75 Sri Lankan families in Hawkes Bay.
Thai monks who lived at the monastery also attended the Vesak celebrations.
The guests walked around a statue of the Buddha in a candlelit procession before snacks were given out.
Mr Ellegala said the Vesak holiday was an immensely popular and colourful event in Sri Lanka.
In Sri Lanka Vesak was celebrated on the full moon of the lunar month of Vesak (usually in the month of May), for about one week.
During this week, the selling of alcohol and fresh meat was usually prohibited.
The Fardon Rd Buddhist monastery, formally called the Pathumrungsiwatanaram Monastery, served as a hub for the Buddhist community whether they were Kiwi, people from Thailand, Laos, Sri Lanka or other countries.
