How does New Zealand enter the World Cup?

New Zealand joined the Oceania Football Association, so New Zealand played the World Cup qualifiers in Oceania (only 32 national teams participated in the World Cup finals, so all continents held qualifiers before the World Cup, and the teams that entered the finals were selected according to the results of the qualifiers. The number of finalists varies from continent to continent, with the highest in Europe 13 and the lowest in Oceania (0.5). If they win the first place in the qualifiers, they will get a ranking of 0.5. Specific arrangements:

The first stage: 10 teams except New Zealand participated in the South Pacific Games, and the top three advanced to the second stage. The second stage: The three teams promoted in the first stage will participate in the second stage together with New Zealand, and the four teams will play home and away games in the league, and the top two will advance to the third stage. The third stage: in the second stage, the two teams will play home and away games, and the winner will play home and away games with the fifth place in Asia, and the winner will win the World Cup.

Note that although Australia belongs to Oceania geographically, the Australian Football Association belongs to the Asian Football Association, so they play the Asian World Cup qualifiers. It is precisely because Australia came to Asia that New Zealand has no strong opponent, so it is easier for New Zealand to get 0.5 places and get closer to the World Cup.
